a612436f14 Merge branch 'tg/stash-push-fixup'
Recent enhancement to "git stash push" command to support pathspec
to allow only a subset of working tree changes to be stashed away
was found to be too chatty and exposed the internal implementation
detail (e.g. when it uses reset to match the index to HEAD before
doing other things, output from reset seeped out).  These, and
other chattyness has been fixed.

* tg/stash-push-fixup:
  stash: keep untracked files intact in stash -k
  stash: pass the pathspec argument to git reset
  stash: don't show internal implementation details

b92ff6e814 sequencer: allow the commit-msg hooks to run during a reword
The `reword` command used to call `git commit` in a manner that asks for
the prepare-commit-msg and commit-msg hooks to do their thing.

Converting that part of the interactive rebase to C code introduced the
regression where those hooks were no longer run.

Let's fix this.

Note: the flag is called `VERIFY_MSG` instead of the more intuitive
`RUN_COMMIT_MSG_HOOKS` to indicate that the flag suppresses the
`--no-verify` flag (which may do other things in the future in addition
to suppressing the commit message hooks, too).

244ea1b5e4 rev-parse: match @{upstream}, @{u} and @{push} case-insensitively
Change the revision parsing logic to match @{upstream}, @{u} & @{push}
case-insensitively.

Before this change supplying anything except the lower-case forms
emits an "unknown revision or path not in the working tree"
error. This change makes upper-case & mixed-case versions equivalent
to the lower-case versions.

The use-case for this is being able to hold the shift key down while
typing @{u} on certain keyboard layouts, which makes the sequence
easier to type, and reduces cases where git throws an error at the
user where it could do what he means instead.

These suffixes now join various other suffixes & special syntax
documented in gitrevisions(7) that matches case-insensitively. A table
showing the status of the various forms documented there before &
after this patch is shown below. The key for the table is:

 - CI  = Case Insensitive
 - CIP = Case Insensitive Possible (without ambiguities)
 - AG  = Accepts Garbage (.e.g. @{./.4.minutes./.})

Before this change:

    |----------------+-----+------+-----|
    | What?          | CI? | CIP? | AG? |
    |----------------+-----+------+-----|
    | @{<date>}      | Y   | Y    | Y   |
    | @{upstream}    | N   | Y    | N   |
    | @{push}        | N   | Y    | N   |
    |----------------+-----+------+-----|

After it:

    |----------------+-----+------+-----|
    | What?          | CI? | CIP? | AG? |
    |----------------+-----+------+-----|
    | @{<date>}      | Y   | Y    | Y   |
    | @{upstream}    | Y   | Y    | N   |
    | @{push}        | Y   | Y    | N   |
    |----------------+-----+------+-----|

The ^{<type>} suffix is not made case-insensitive, because other
places that take <type> like "cat-file -t <type>" do want them case
sensitively (after all we never declared that type names are case
insensitive). Allowing case-insensitive typename only with this syntax
will make the resulting Git as a whole inconsistent.

This change was independently authored to scratch a longtime itch, but
when I was about to submit it I discovered that a similar patch had
been submitted unsuccessfully before by Conrad Irwin in August 2011 as
"rev-parse: Allow @{U} as a synonym for
@{u}" (<1313287071-7851-1-git-send-email-conrad.irwin@gmail.com>).

The tests for this patch are more exhaustive than in the 2011
submission. The starting point for them was to first change the code
to only support upper-case versions of the existing words, seeing what
broke, and amending the breaking tests to check upper case & mixed
case as appropriate, and where not redundant to other similar
tests. The implementation itself is equivalent.

af6865a7f1 submodule.c: convert is_submodule_modified to use strbuf_getwholeline
Instead of implementing line reading yet again, make use of our beautiful
library function to read one line.  By using strbuf_getwholeline instead
of strbuf_read, we avoid having to allocate memory for the entire child
process output at once.  That is, we limit maximum memory usage.
Also we can start processing the output as it comes in, no need to
wait for all of it.

Once we know all information that we care about, we can terminate
the child early. In that case we do not care about its exit code as well.
By just closing our side of the pipe the child process will get a SIGPIPE
signal, which it will not report nor do we report it in finish_command,
ac78663b0d (run-command: don't warn on SIGPIPE deaths, 2015-12-29).

a54e938e5b strbuf: support long paths w/o read rights in strbuf_getcwd() on FreeBSD
FreeBSD implements getcwd(3) as a syscall, but falls back to a version
based on readdir(3) if it fails for some reason.  The latter requires
permissions to read and execute path components, while the former does
not.  That means that if our buffer is too small and we're missing
rights we could get EACCES, but we may succeed with a bigger buffer.

Keep retrying if getcwd(3) indicates lack of permissions until our
buffer can fit PATH_MAX bytes, as that's the maximum supported by the
syscall on FreeBSD anyway.  This way we do what we can to be able to
benefit from the syscall, but we also won't loop forever if there is a
real permission issue.

This fixes a regression introduced with 7333ed17 (setup: convert
setup_git_directory_gently_1 et al. to strbuf, 2014-07-28) for paths
longer than 127 bytes with components that miss read or execute
permissions (e.g. 0711 on /home for privacy reasons); we used a fixed
PATH_MAX-sized buffer before.

ac3f5a3468 ref-filter: add --no-contains option to tag/branch/for-each-ref
Change the tag, branch & for-each-ref commands to have a --no-contains
option in addition to their longstanding --contains options.

This allows for finding the last-good rollout tag given a known-bad
<commit>. Given a hypothetically bad commit cf5c7253e0, the git
version to revert to can be found with this hacky two-liner:

    (git tag -l 'v[0-9]*'; git tag -l --contains cf5c7253e0 'v[0-9]*') |
        sort | uniq -c | grep -E '^ *1 ' | awk '{print $2}' | tail -n 10

With this new --no-contains option the same can be achieved with:

    git tag -l --no-contains cf5c7253e0 'v[0-9]*' | sort | tail -n 10

As the filtering machinery is shared between the tag, branch &
for-each-ref commands, implement this for those commands too. A
practical use for this with "branch" is e.g. finding branches which
were branched off between v2.8.0 and v2.10.0:

    git branch --contains v2.8.0 --no-contains v2.10.0

The "describe" command also has a --contains option, but its semantics
are unrelated to what tag/branch/for-each-ref use --contains for. A
--no-contains option for "describe" wouldn't make any sense, other
than being exactly equivalent to not supplying --contains at all,
which would be confusing at best.

Add a --without option to "tag" as an alias for --no-contains, for
consistency with --with and --contains.  The --with option is
undocumented, and possibly the only user of it is
Junio (<xmqqefy71iej.fsf@gitster.mtv.corp.google.com>). But it's
trivial to support, so let's do that.

The additions to the the test suite are inverse copies of the
corresponding --contains tests. With this change --no-contains for
tag, branch & for-each-ref is just as well tested as the existing
--contains option.

In addition to those tests, add a test for "tag" which asserts that
--no-contains won't find tree/blob tags, which is slightly
unintuitive, but consistent with how --contains works & is documented.

Change the --points-at option to default to HEAD for consistency with
its siblings --contains, --merged etc. which default to
HEAD. Previously we'd get:

    $ git tag --points-at 2>&1 | head -n 1
    error: option `points-at' requires a value

This changes behavior added in commit ae7706b9ac (tag: add --points-at
list option, 2012-02-08).

6a338149f6 tag: implicitly supply --list given another list-like option
Change the "tag" command to implicitly turn on its --list mode when
provided with a list-like option such as --contains, --points-at etc.

This is for consistency with how "branch" works. When "branch" is
given a list-like option, such as --contains, it implicitly provides
--list. Before this change "tag" would error out on those sorts of
invocations. I.e. while both of these worked for "branch":

    git branch --contains v2.8.0 <pattern>
    git branch --list --contains v2.8.0 <pattern>

Only the latter form worked for "tag":

    git tag --contains v2.8.0 '*rc*'
    git tag --list --contains v2.8.0 '*rc*'

Now "tag", like "branch", will implicitly supply --list when a
list-like option is provided, and no other conflicting non-list
options (such as -d) are present on the command-line.

Spelunking through the history via:

    git log --reverse -p -G'only allowed with' -- '*builtin*tag*c'

Reveals that there was no good reason for not allowing this in the
first place. The --contains option added in 32c35cfb1e ("git-tag: Add
--contains option", 2009-01-26) made this an error. All the other
subsequent list-like options that were added copied its pattern of
making this usage an error.

The only tests that break as a result of this change are tests that
were explicitly checking that this "branch-like" usage wasn't
permitted. Change those failing tests to check that this invocation
mode is permitted, add extra tests for the list-like options we
weren't testing, and tests to ensure that e.g. we don't toggle the
list mode in the presence of other conflicting non-list options.

With this change errors messages such as "--contains option is only
allowed with -l" don't make sense anymore, since options like
--contain turn on -l. Instead we error out when list-like options such
as --contain are used in conjunction with conflicting options such as
-d or -v.

c485b24c42 tag: change misleading --list <pattern> documentation
Change the documentation for --list so that it's described as a
toggle, not as an option that takes a <pattern> as an argument.

Junio initially documented this in b867c7c23a ("git-tag: -l to list
tags (usability).", 2006-02-17), but later Jeff King changed "tag" to
accept multiple patterns in 588d0e834b ("tag: accept multiple patterns
for --list", 2011-06-20).

However, documenting this as "-l <pattern>" was never correct, as
these both worked before Jeff's change:

    git tag -l 'v*'
    git tag 'v*' -l

One would expect an option that was documented like that to only
accept:

    git tag --list
    git tag --list 'v*rc*'

And after Jeff's change, one that took multiple patterns:

    git tag --list 'v*rc*' --list '*2.8*'

But since it's actually a toggle all of these work as well, and
produce identical output to the last example above:

    git tag --list 'v*rc*' '*2.8*'
    git tag --list 'v*rc*' '*2.8*' --list --list --list
    git tag --list 'v*rc*' '*2.8*' --list -l --list -l --list

Now the documentation is more in tune with how the "branch" command
describes its --list option since commit cddd127b9a ("branch:
introduce --list option", 2011-08-28).

Change the test suite to assert that these invocations work for the
cases that weren't already being tested for.

b42ca35e5c t7004, t7030: fix here-doc syntax errors
Jan Palus noticed that some here-doc are spelled incorrectly,
resulting the entire remainder of the test snippet being slurped
into the "expect" file as if it were data, e.g. in this sequence

	cat >expect <<EOF &&
	... expectation ...
	EOF
	git $cmd_being_tested >actual &&
	test_cmp expect actual

the last command of the test is "cat" that sends everything to
'expect' and succeeds.

Fixing these issues in t7004 and t7030 reveals that "git tag -v"
and "git verify-tag" with their --format option do not work as the
test was expecting originally.  Instead of showing both valid tags
and tags with incorrect signatures on their output, tags that do not
pass verification are omitted from the output.  Another breakage that
is uncovered is that these tests must be restricted to environment
where gpg is available.

Arguably, that is a safer behaviour, and because the format
specifiers like %(tag) do not have a way to show if the signature
verifies correctly, the command with the --format option cannot be
used to get a list of tags annotated with their signature validity
anyway.

For now, let's fix the here-doc syntax, update the expectation to
match the reality, and update the test prerequisite.

Maybe later when we extend the --format language available to "git
tag -v" and "git verify-tag" to include things like "%(gpg:status)",
we may want to change the behaviour so that piping a list of tag
names into

    xargs git verify-tag --format='%(gpg:status) %(tag)'

becomes a good way to produce such a list, but that is a separate
topic.

end-of-here-doc marker that is incorrectly spelled, e.g.

	git some command >actual &&

which ends up slurping the entire remainder of the script as if it

fef56eb006 completion: fill COMPREPLY directly when completing refs
__gitcomp_nl() iterates over all the possible completion words it gets
as argument

  - filtering matching words,
  - appending a trailing space to each matching word (in all but two
    cases),
  - prepending a prefix to each matching word (when completing words
    after e.g. '--option=<TAB>' or 'master..<TAB>'), and
  - adding each matching word to the COMPREPLY array.

This takes a while when a lot of refs are passed to __gitcomp_nl().

The previous changes in this series ensure that __git_refs() lists
only refs matching the current word to be completed, making a second
filtering in __gitcomp_nl() redundant.

Adding the necessary prefix and suffix could be done in __git_refs()
as well:

  - When refs come from 'git for-each-ref', then that prefix and
    suffix could be added much more efficiently using a 'git
    for-each-ref' format containing said prefix and suffix.  Care
    should be taken, though, because that prefix might contain
    'for-each-ref' format specifiers as part of the left hand side of
    a '..' range or '...' symmetric difference notation or
    fetch/push/etc. refspec, e.g. 'git log "evil-%(refname)..br<TAB>'.
    Doubling every '%' in the prefix will prevent 'git for-each-ref'
    from interpolating any of those contained specifiers.
  - When refs come from 'git ls-remote', then that prefix and suffix
    can be added in the shell loop that has to process 'git
    ls-remote's output anyway.
  - Finally, the prefix and suffix can be added to that handful of
    potentially matching symbolic and pseudo refs right away in the
    shell loop listing them.

And then all what is still left to do is to assign a bunch of
newline-separated words to a shell array, which can be done without a
shell loop iterating over each word, basically making all of
__gitcomp_nl() unnecessary for refs completion.

Add the helper function __gitcomp_direct() to fill the COMPREPLY array
with prefiltered and preprocessed words without any additional
processing, without a shell loop, with just one single compound
assignment.  Modify __git_refs() to accept prefix and suffix
parameters and add them to each and every listed ref as described
above.  Modify __git_complete_refs() to pass the prefix and suffix
parameters to __git_refs() and to feed __git_refs()'s output to
__gitcomp_direct() instead of __gitcomp_nl().

This speeds up refs completion when there are a lot of refs matching
the current word to be completed.  Listing all branches for completion
in a repo with 100k local branches, all packed, best of five:

e896369beb completion: let 'for-each-ref' and 'ls-remote' filter matching refs
When completing refs, several __git_refs() code paths list all the
refs from the refs/{heads,tags,remotes}/ hierarchy and then
__gitcomp_nl() iterates over those refs in a shell loop to filter out
refs not matching the current ref to be completed.  This comes with a
considerable performance penalty when a repository contains a lot of
refs but the current ref can be uniquely completed or when only a
handful of refs match the current ref.

Reduce the number of iterations in __gitcomp_nl() from the number of
refs to the number of matching refs by specifying appropriate globbing
patterns to 'git for-each-ref' and 'git ls-remote' to list only those
refs that match the current ref to be completed.  However, do so only
when the ref to match is explicitly given as parameter, because the
current word on the command line might contain a prefix like
'--option=' or 'branch..'.  The __git_complete_refs() and
__git_complete_fetch_refspecs() helpers introduced previously in this
patch series already call __git_refs() specifying this current ref
parameter, so all their callsites, i.e. all places in the completion
script doing refs completion, can benefit from this optimization.

Furthermore, list only those symbolic and pseudo refs that match the
current ref to be completed.  Though it doesn't matter at all in
itself performance-wise, it will allow us further significant
optimizations later in this series.

This speeds up refs completion considerably when there are a lot of
non-matching refs to be filtered out.  Uniquely completing a branch in
a repository with 100k local branches, all packed, best of five:

aa0644f74f completion: support completing fully qualified non-fast-forward refspecs
After 'git fetch <remote> <TAB>' our completion script offers refspecs
that will fetch to a local branch with the same name as in the remote
repository, e.g. 'master:master'.  This also completes
non-fast-forward refspecs, i.e. after a '+' prefix like
'+master:master', and fully qualified refspecs, e.g.
'refs/heads/master:refs/heads/master'.  However, it does not complete
non-fast-forward fully qualified refspecs (or fully qualified refspecs
following any other prefix, e.g. '--option=', though currently no git
command supports such an option, but third party git commands might).

These refspecs are listed by the __git_refs2() function, which is just
a thin wrapper iterating over __git_refs()'s output, turning each
listed ref into a refspec.  Now, it's certainly possible to modify
__git_refs2() and its callsite to pass an extra parameter containing
only the ref part of the current word to be completed (to follow suit
of the previous commit) to deal with prefixed fully qualified refspecs
as well.  Unfortunately, keeping the current behavior unchanged in the
"no extra parameter" case brings in a bit of subtlety, which makes the
resulting code ugly and compelled me to write a 8-line long comment in
the proof of concept.  Not good.  However, since the callsite has to
be modified for proper functioning anyway, we might as well leave
__git_refs2() as is and introduce a new helper function without
backwards compatibility concerns.

Add the new function __git_complete_fetch_refspecs() that has all the
necessary parameters to do the right thing in all cases mentioned
above, including non-fast-forward fully qualified refspecs.  This new
function can also easier benefit from optimizations coming later in
this patch series.

2ea328a119 completion: support completing full refs after '--option=refs/<TAB>'
Completing full refs currently only works when the full ref stands on
in its own on the command line, but doesn't work when the current word
to be completed contains a prefix before the full ref, e.g.
'--option=refs/<TAB>' or 'master..refs/bis<TAB>'.

The reason is that __git_refs() looks at the current word to be
completed ($cur) as a whole to decide whether it has to list full (if
it starts with 'refs/') or short refs (otherwise).  However, $cur also
holds said '--option=' or 'master..' prefixes, which of course throw
off this decision.  Luckily, the default action is to list short refs,
that's why completing short refs happens to work even after a
'master..<TAB>' prefix and similar cases.

Pass only the ref part of the current word to be completed to
__git_refs() as a new positional parameter, so it can make the right
decision even if the whole current word contains some kind of a
prefix.

Make this new parameter the 4. positional parameter and leave the 3.
as an ignored placeholder for now (it will be used later in this patch
series).

15b4a16395 completion: wrap __git_refs() for better option parsing
__git_refs() currently accepts two optional positional parameters: a
remote and a flag for 'git checkout's tracking DWIMery.  To fix a
minor bug, and, more importantly, for faster refs completion, this
series will add three more parameters: a prefix, the current word to
be completed and a suffix, i.e. the options accepted by __gitcomp() &
friends, and will change __git_refs() to list only refs matching that
given current word and to add that given prefix and suffix to the
listed refs.

However, __git_refs() is the helper function that is most likely used
in users' custom completion scriptlets for their own git commands, and
we don't want to break those, so

  - we can't change __git_refs()'s default output format, i.e. we
    can't by default append a trailing space to every listed ref,
    meaning that the suffix parameter containing the default trailing
    space would have to be specified on every invocation, and

  - we can't change the position of existing positional parameters
    either, so there would have to be plenty of set-but-empty
    placeholder positional parameters all over the completion script.

Furthermore, with five positional parameters it would be really hard
to remember which position means what.

To keep callsites simple, add the new wrapper function
__git_complete_refs() around __git_refs(), which:

  - instead of positional parameters accepts real '--opt=val'-style
    options and with minimalistic option parsing translates them to
    __git_refs()'s and __gitcomp_nl()'s positional parameters, and

  - includes the '__gitcomp_nl "$(__git_refs ...)" ...' command
    substitution to make its behavior match its name and the behavior
    of other __git_complete_* functions, and to limit future changes
    in this series to __git_refs() and this new wrapper function.

Call this wrapper function instead of __git_refs() wherever possible
throughout the completion script, i.e. when __git_refs()'s output is
fed to __gitcomp_nl() right away without further processing, which
means all callsites except a single one in the __git_refs2() helper.

e0e7f99ea4 stash: keep untracked files intact in stash -k
Currently when there are untracked changes in a file "one" and in a file
"two" in the repository and the user uses:

    git stash push -k one

all changes in "two" are wiped out completely.  That is clearly not the
intended result.  Make sure that only the files given in the pathspec
are changed when git stash push -k <pathspec> is used.

869fb8f729 stash: pass the pathspec argument to git reset
For "git stash -p --no-keep-index", the pathspec argument is currently
not passed to "git reset".  This means that changes that are staged but
that are excluded from the pathspec still get unstaged by git stash -p.

Make sure that doesn't happen by passing the pathspec argument to the
git reset in question, bringing the behaviour in line with "git stash --

1790f4fea0 stash: don't show internal implementation details
git stash push uses other git commands internally.  Currently it only
passes the -q flag to those if the -q flag is passed to git stash.  when
using 'git stash push -p -q --no-keep-index', it doesn't even pass the

It really is enough for the user to know that the stash is created,
without bothering them with the internal details of what's happening.
Always pass the -q flag to the internal git clean and git reset
commands, to avoid unnecessary and potentially confusing output.

b0176ce6b5 builtin/describe: introduce --broken flag
git-describe tells you the version number you're at, or errors out, e.g.
when you run it outside of a repository, which may happen when downloading
a tar ball instead of using git to obtain the source code.

To keep this property of only erroring out, when not in a repository,
severe (submodule) errors must be downgraded to reporting them gently
instead of having git-describe error out completely.

To achieve that a flag '--broken' is introduced, which is in the same
vein as '--dirty' but uses an actual child process to check for dirtiness.
When that child dies unexpectedly, we'll append '-broken' instead of
'-dirty'.

a1be47e4ca hash-object: fix buffer reuse with --path in a subdirectory
The hash-object command uses prefix_filename() without
duplicating its return value. Since that function returns a
static buffer, the value is overwritten by subsequent calls.

This can cause incorrect results when we use --path along
with hashing a file by its relative path, both of which need
to call prefix_filename(). We overwrite the filename
computed for --path, effectively ignoring it.

We can fix this by calling xstrdup on the return value. Note
that we don't bother freeing the "vpath" instance, as it
remains valid until the program exit.

3e5584ca61 t1400: set core.logAllRefUpdates in "logged by touch" tests
A group of update-ref tests verifies that logs are created when either
the log file for the ref already exists or core.logAllRefUpdates is
"true".  However, when the default for core.logAllRefUpdates was
changed in 0bee59186 (Enable reflogs by default in any repository with
a working directory., 2006-12-14), the setup for the tests was not
updated.  As a result, the "logged by touch" tests would pass even if
the log file did not exist (i.e., if "--create-reflog" was removed
from the first "git update-ref" call).

Update the "logged by touch" tests to disable core.logAllRefUpdates
explicitly so that the behavior does not depend on the default value.
While we're here, update the "logged by config" tests to use
test_config() rather than setting core.logAllRefUpdates to "true"
outside of the tests.

f53c5de29c pickaxe: fix segfault with '-S<...> --pickaxe-regex'
'git {log,diff,...} -S<...> --pickaxe-regex' can segfault as a result
of out-of-bounds memory reads.

diffcore-pickaxe.c:contains() looks for all matches of the given regex
in a buffer in a loop, advancing the buffer pointer to the end of the
last match in each iteration.  When we switched to REG_STARTEND in
b7d36ffca (regex: use regexec_buf(), 2016-09-21), we started passing
the size of that buffer to the regexp engine, too.  Unfortunately,
this buffer size is never updated on subsequent iterations, and as the
buffer pointer advances on each iteration, this "bufptr+bufsize"
points past the end of the buffer.  This results in segmentation
fault, if that memory can't be accessed.  In case of 'git log' it can
also result in erroneously listed commits, if the memory past the end
of buffer is accessible and happens to contain data matching the
regex.

Reduce the buffer size on each iteration as the buffer pointer is
advanced, thus maintaining the correct end of buffer location.
Furthermore, make sure that the buffer pointer is not dereferenced in
the control flow statements when we already reached the end of the
buffer.

The new test is flaky, I've never seen it fail on my Linux box even
without the fix, but this is expected according to db5dfa3 (regex:
-G<pattern> feeds a non NUL-terminated string to regexec() and fails,
2016-09-21).  However, it did fail on Travis CI with the first (and
incomplete) version of the fix, and based on that commit message I
would expect the new test without the fix to fail most of the time on
Windows.

When the 'test_pause' helper function invokes the shell mid-test, it
explicitly redirects the shell's stdout and stderr to file descriptors
3 and 4, which are the stdout and stderr of the tests (i.e. where they
would be connected anyway without those redirections).  These file
descriptors are only attached to the terminal in verbose mode, hence
the restriction of 'test_pause' to work only with '-v'.

Redirect the shell's stdout and stderr to the test environment's
original stdout and stderr, allowing it to work properly even in
non-verbose mode, and the restriction can be lifted.

4ecae3c8c1 tests: create an interactive gdb session with the 'debug' helper
The 'debug' test helper is supposed to facilitate debugging by running
a command of the test suite under gdb.  Unfortunately, its usefulness
is severely limited, because that gdb session is not interactive,
since the test's, and thus gdb's standard input is redirected from
/dev/null (for a good reason, see 781f76b15 (test-lib: redirect stdin
of tests, 2011-12-15)).

Redirect gdb's standard file descriptors from/to the test
environment's stdin, stdout and stderr in the 'debug' helper, thus
creating an interactive gdb session (even in non-verbose mode), which
is much, much more useful.

bb62e0a99f clone: teach --recurse-submodules to optionally take a pathspec
Teach clone --recurse-submodules to optionally take a pathspec argument
which describes which submodules should be recursively initialized and
cloned.  If no pathspec is provided, --recurse-submodules will
recursively initialize and clone all submodules by using a default
pathspec of ".".  In order to construct more complex pathspecs,
--recurse-submodules can be given multiple times.

This also configures the 'submodule.active' configuration option to be
the given pathspec, such that any future invocation of `git submodule
update` will keep up with the pathspec.

Additionally the switch '--recurse' is removed from the Documentation as
well as marked hidden in the options array, to streamline the options
for submodules.  A simple '--recurse' doesn't convey what is being
recursed, e.g. it could mean directories or trees (c.f. ls-tree) In a
lot of other commands we already have '--recurse-submodules' to mean
recursing into submodules, so advertise this spelling here as the
genuine option.

a086f921a7 submodule: decouple url and submodule interest
Currently the submodule.<name>.url config option is used to determine if
a given submodule is of interest to the user.  This ends up being
cumbersome in a world where we want to have different submodules checked
out in different worktrees or a more generalized mechanism to select
which submodules are of interest.

In a future with worktree support for submodules, there will be multiple
working trees, each of which may only need a subset of the submodules
checked out.  The URL (which is where the submodule repository can be
obtained) should not differ between different working trees.

It may also be convenient for users to more easily specify groups of
submodules they are interested in as opposed to running "git submodule
init <path>" on each submodule they want checked out in their working
tree.

To this end two config options are introduced, submodule.active and
submodule.<name>.active.  The submodule.active config holds a pathspec
that specifies which submodules should exist in the working tree.  The
submodule.<name>.active config is a boolean flag used to indicate if
that particular submodule should exist in the working tree.

Its important to note that submodule.active functions differently than
the other configuration options since it takes a pathspec.  This allows
users to adopt at least two new workflows:

  1. Submodules can be grouped with a leading directory, such that a
     pathspec e.g. 'lib/' would cover all library-ish modules to allow
     those who are interested in library-ish modules to set
     "submodule.active = lib/" just once to say any and all modules in
     'lib/' are interesting.

  2. Once the pathspec-attribute feature is invented, users can label
     submodules with attributes to group them, so that a broad pathspec
     with attribute requirements, e.g. ':(attr:lib)', can be used to say
     any and all modules with the 'lib' attribute are interesting.
     Since the .gitattributes file, just like the .gitmodules file, is
     tracked by the superproject, when a submodule moves in the
     superproject tree, the project can adjust which path gets the
     attribute in .gitattributes, just like it can adjust which path has
     the submodule in .gitmodules.

Neither of these two additional configuration options solve the problem
of wanting different submodules checked out in different worktrees
because multiple worktrees share .git/config.  Only once per-worktree
configurations become a reality can this be solved, but this is a
necessary preparatory step for that future.

Given these multiple ways to check if a submodule is of interest, the
more fine-grained submodule.<name>.active option has the highest order
of precedence followed by the pathspec check against submodule.active.
To ensure backwards compatibility, if neither of these options are set,
git falls back to checking the submodule.<name>.url option to determine
if a submodule is interesting.

b2dfeb7c00 ls-files: fix bug when recursing with relative pathspec
When using the --recurse-submodules flag with a relative pathspec which
includes "..", an error is produced inside the child process spawned for a
submodule.  When creating the pathspec struct in the child, the ".." is
interpreted to mean "go up a directory" which causes an error stating that the
path ".." is outside of the repository.

While it is true that ".." is outside the scope of the submodule, it is
confusing to a user who originally invoked the command where ".." was indeed
still inside the scope of the superproject.  Since the child process launched
for the submodule has some context that it is operating underneath a
superproject, this error could be avoided.

This patch fixes the bug by passing the 'prefix' to the child process.  Now
each child process that works on a submodule has two points of reference to the
superproject: (1) the 'super_prefix' which is the path from the root of the
superproject down to root of the submodule and (2) the 'prefix' which is the
path from the root of the superproject down to the directory where the user
invoked the git command.

With these two pieces of information a child process can correctly interpret
the pathspecs provided by the user as well as being able to properly format its
output relative to the directory the user invoked the original command from.
