f6a5279977 submodule deinit: require '--all' instead of '.' for all submodules
The discussion in [1] pointed out that '.' is a faulty suggestion as
there is a corner case where it fails:

> "submodule deinit ." may have "worked" in the sense that you would
> have at least one path in your tree and avoided this "nothing
> matches" most of the time.  It would have still failed with the
> exactly same error if run in an empty repository, i.e.
>
>        $ E=/var/tmp/x/empty && rm -fr "$E" && mkdir -p "$E" && cd "$E"
>        $ git init
>        $ rungit v2.6.6 submodule deinit .
>        error: pathspec '.' did not match any file(s) known to git.
>        Did you forget to 'git add'?
>        $ >file && git add file
>        $ rungit v2.6.6 submodule deinit .
>        $ echo $?
>        0

So instead of a pathspec add the '--all' option to deinit all submodules
and add a test to check for the corner case of an empty repository.

The code only needs to learn about the '--all' option and doesn't
require further changes as `git submodule--helper list "$@"` will list
all submodules when "$@" is empty.

de45dbb818 t7507-commit-verbose: improve test coverage by testing number of diffs
Make the fake "editor" store output of grep in a file so that we can
see how many diffs were contained in the message and use them in
individual tests where ever it is required. A subsequent commit will
introduce scenarios where it is important to be able to exactly
determine how many diffs were present.

The fake "editor" is always made to succeed regardless of whether grep
found diff headers or not so that we don't have to use 'test_must_fail'
for which 'test_line_count = 0' is an easy substitute and also helps in
maintaining the consistency.

Also use write_script() to create the fake "editor".

e0070e8bd5 parse-options.c: make OPTION_COUNTUP respect "unspecified" values
OPT_COUNTUP() merely increments the counter upon --option, and resets it
to 0 upon --no-option, which means that there is no "unspecified" value
with which a client can initialize the counter to determine whether or
not --[no]-option was seen at all.

Make OPT_COUNTUP() treat any negative number as an "unspecified" value
to address this shortcoming. In particular, if a client initializes the
counter to -1, then if it is still -1 after parse_options(), then
neither --option nor --no-option was seen; if it is 0, then --no-option
was seen last, and if it is 1 or greater, than --option was seen last.

This change does not affect the behavior of existing clients because
they all use the initial value of 0 (or more).

Note that builtin/clean.c initializes the variable used with
OPT__FORCE (which uses OPT_COUNTUP()) to a negative value, but it is set
to either 0 or 1 by reading the configuration before the code calls
parse_options(), i.e. as far as parse_options() is concerned, the
initial value of the variable is not negative.

To test this behavior, in test-parse-options.c, "verbose" is set to
"unspecified" while quiet is set to 0 which will test the new behavior
with all sets of values.

867ad08a26 hooks: allow customizing where the hook directory is
Change the hardcoded lookup for .git/hooks/* to optionally lookup in
$(git config core.hooksPath)/* instead.

This is essentially a more intrusive version of the git-init ability to
specify hooks on init time via init templates.

The difference between that facility and this feature is that this can
be set up after the fact via e.g. ~/.gitconfig or /etc/gitconfig to
apply for all your personal repositories, or all repositories on the
system.

I plan on using this on a centralized Git server where users can create
arbitrary repositories under /gitroot, but I'd like to manage all the
hooks that should be run centrally via a unified dispatch mechanism.

de0824ed8f githooks.txt: minor improvements to the grammar & phrasing
Change:

 * Sentences that needed "the" or "a" to either add those or change them
   so they don't need them.

 * The little tangent about "You can use this to do X (if your project
   wants to do X)" can just be shortened to "if you want to do X".

 * s/parameter/parameters/ when the plural made more sense.

Most of this goes all the way back to the initial introduction of
hooks.txt in 6d35cc76 (Document hooks., 2005-09-02).

bf7d977f8c githooks.txt: amend dangerous advice about 'update' hook ACL
Any ACL you implement via an 'update' hook isn't actual access control
if the user has login access to the machine running git, because they
can trivially just build their own version of Git which doesn't run the
hook.

Change the documentation to take this dangerous edge case into account,
and remove the mention of the advice originating on the mailing list,
the users reading this don't care where the idea came up.

49fa52fd00 githooks.txt: improve the intro section
Change the documentation so that:

 * We don't talk about "little scripts". Hooks can be as big as you
   want, and don't have to be scripts, just call them "programs".

 * We note that we change the working directory before a hook is called,
   nothing documented this explicitly, but the current behavior is
   predictable. It helps a lot to know what directory these hooks will
   be executed from.

 * We don't make claims about the example hooks which may not be true
   depending on the configuration of 'init.templateDir'. Clarify that
   we're talking about the default settings of git-init in those cases,
   and move some of this documentation into git-init's documentation
   about the default templates.

 * We briefly note in the intro that hooks can get their arguments in
   various different ways, and that how exactly is described below for
   each hook.

309ca68e5a Merge branch 'js/name-rev-use-oldest-ref'
"git describe --contains" often made a hard-to-justify choice of
tag to give name to a given commit, because it tried to come up
with a name with smallest number of hops from a tag, causing an old
commit whose close descendant that is recently tagged were not
described with respect to an old tag but with a newer tag.  It did
not help that its computation of "hop" count was further tweaked to
penalize being on a side branch of a merge.  The logic has been
updated to favor using the tag with the oldest tagger date, which
is a lot easier to explain to the end users: "We describe a commit
in terms of the (chronologically) oldest tag that contains the
commit."

029f37217c gitweb: apply fallback encoding before highlight
Some multi-byte character encodings (such as Shift_JIS and GBK) have
characters whose final bytes is an ASCII '\' (0x5c), and they
will be displayed as funny-characters even if $fallback_encoding is
correct.  This is because `highlight` command always expects UTF-8
encoded strings from STDIN.

    $ echo 'my $v = "申";' | highlight --syntax perl | w3m -T text/html -dump
    my $v = "申";

    $ echo 'my $v = "申";' | iconv -f UTF-8 -t Shift_JIS | highlight \
        --syntax perl | iconv -f Shift_JIS -t UTF-8 | w3m -T text/html -dump

    iconv: (stdin):9:135: cannot convert
    my $v = "

This patch prepare git blob objects to be encoded into UTF-8 before
highlighting in the manner of `to_utf8` subroutine.

6694856153 commit-tree: do not pay attention to commit.gpgsign
ba3c69a9 (commit: teach --gpg-sign option, 2011-10-05) introduced a
"signed commit" by teaching the --[no]-gpg-sign option and the
commit.gpgsign configuration variable to various commands that
create commits.

Teaching these to "git commit" and "git merge", both of which are
end-user facing Porcelain commands, was perfectly fine.  Allowing
the plumbing "git commit-tree" to suddenly change the behaviour to
surprise the scripts by paying attention to commit.gpgsign was not.

Among the in-tree scripts, filter-branch, quiltimport, rebase and
stash are the commands that run "commit-tree".  If any of these
wants to allow users to always sign every single commit, they should
offer their own configuration (e.g. "filterBranch.gpgsign") with an
option to disable signing (e.g. "git filter-branch --no-gpgsign").

Ignoring commit.gpgsign option _obviously_ breaks the backward
compatibility, but it is easy to follow the standard pattern in
scripts to honor whatever configuration variable they choose to
follow.  E.g.

	case $(git config --bool commit.gpgsign) in
	true) sign=-S ;;
	*) sign= ;;
	esac &&
	git commit-tree $sign ...whatever other args...

Do so to make sure that "git rebase" keeps paying attention to the
configuration variable, which unfortunately is a documented mistake.

c66410ed32 submodule init: redirect stdout to stderr
Reroute the output of stdout to stderr as it is just informative
messages, not to be consumed by machines.

This should not regress any scripts that try to parse the
current output, as the output is already internationalized
and therefore unstable.

We want to init submodules from the helper for `submodule update`
in a later patch and the stdout output of said helper is consumed
by the parts of `submodule update` which are still written in shell.
So we have to be careful which messages are on stdout.

fa7224589f .mailmap: update to my shorter email address
Following f916ab0ccc ("send-email: more meaningful Message-ID"),
my own email address is too long :x

While I could have an even shorter address by one character with
"yhbt.net", "80x24.org" is more representative of my
hacking-related pursuits.

bb05510e55 t5510: run auto-gc in the foreground
The last test added to 't5510-fetch' in 0898c96281 (fetch: release
pack files before garbage-collecting, 2016-01-13) may sporadically
trigger following error message from the test harness:

  rm: cannot remove 'trash directory.t5510-fetch/auto-gc/.git': Directory not empty

The test in question forces an auto-gc, which, if the system supports
it, runs in the background by default, and occasionally takes long
enough for the test to finish and for 'test_done' to start
housekeeping.  This can lead to the test's 'git gc --auto' in the
background and 'test_done's 'rm -rf $trash' in the foreground racing
each other to create and delete files and directories.  It might just
happen that 'git gc' re-creates a directory that 'rm -rf' already
visited and removed, which ultimately triggers the above error.

Disable detaching the auto-gc process to ensure that it finishes
before the test can continue, thus avoiding this racy situation.
