Rename detection logic in "diff" family that is used in "merge" has
learned to guess when all of x/a, x/b and x/c have moved to z/a,
z/b and z/c, it is likely that x/d added in the meantime would also
want to move to z/d by taking the hint that the entire directory

f78ab355e7 filter-branch: fix errors caused by refs that point at non-committish
"git filter-branch -- --all" prints error messages when processing refs that
point at objects that are not committish. Such refs can be created by
"git replace" with trees or blobs. And also "git tag" with trees or blobs can
create such refs.

Filter these problematic refs out early, before they are seen by the logic to
see which refs have been modified and which have been left intact (which is
where the unwanted error messages come from), and warn that these refs are left
unwritten while doing so.

9f642a7169 completion: add --option completion for most builtin commands
Many builtin commands use parseopt which can expose the option list
via --git-completion-helper but do not have explicit support in
git-completion.bash. This patch detects those commands and uses
__gitcomp_builtin for option completion.

This does not pollute the command name completion though. "git <tab>"
will show you the same set as before. This only kicks in when you type
the correct command name.

8b0eaa41f2 completion: clear cached --options when sourcing the completion script
The established way to update the completion script in an already
running shell is to simply source it again: this brings in any new
--options and features, and clears caching variables.  E.g. it clears
the variables caching the list of (all|porcelain) git commands, so
when they are later lazy-initialized again, then they will list and
cache any newly installed commmands as well.

Unfortunately, since d401f3debc (git-completion.bash: introduce
__gitcomp_builtin, 2018-02-09) and subsequent patches this doesn't
work for a lot of git commands' options.  To eliminate a lot of
hard-to-maintain hard-coded lists of options, those commits changed
the completion script to use a bunch of programmatically created and
lazy-initialized variables to cache the options of those builtin
porcelain commands that use parse-options.  These variables are not
cleared upon sourcing the completion script, therefore they continue
caching the old lists of options, even when some commands recently
learned new options or when deprecated options were removed.

Always 'unset' these variables caching the options of builtin commands
when sourcing the completion script.

Redirect 'unset's stderr to /dev/null, because ZSH's 'unset' complains
if it's invoked without any arguments, i.e. no variables caching
builtin's options are set.  This can happen, if someone were to source
the completion script twice without completing any --options in
between.  Bash stays silent in this case.

Add tests to ensure that these variables are indeed cleared when the
completion script is sourced; not just the variables caching options,
but all other caching variables, i.e. the variables caching commands,
porcelain commands and merge strategies as well.

d319bb18b1 stash push -u: don't create empty stash
When introducing the stash push feature, and thus allowing users to pass
in a pathspec to limit the files that would get stashed in
df6bba0937 ("stash: teach 'push' (and 'create_stash') to honor
pathspec", 2017-02-28), this developer missed one place where the
pathspec should be passed in.

Namely in the call to the 'untracked_files()' function in the
'no_changes()' function.  This resulted in 'git stash push -u --
<non-existant>' creating an empty stash when there are untracked files
in the repository other that don't match the pathspec.

As 'git stash' never creates empty stashes, this behaviour is wrong and
confusing for users.  Instead it should just show a message "No local
changes to save", and not create a stash.

Luckily the 'untracked_files()' function already correctly respects
pathspecs that are passed to it, so the fix is simply to pass the
pathspec along to the function.

833622a945 stash push: avoid printing errors
'git stash push -u -- <pathspec>' prints the following errors if
<pathspec> only matches untracked files:

    fatal: pathspec 'untracked' did not match any files
    error: unrecognized input

This is because we first clean up the untracked files using 'git clean
<pathspec>', and then use a command chain involving 'git add -u
<pathspec>' and 'git apply' to clear the changes to files that are in
the index and were stashed.

As the <pathspec> only includes untracked files that were already
removed by 'git clean', the 'git add' call will barf, and so will 'git
apply', as there are no changes that need to be applied.

Fix this by avoiding the 'git clean' if a pathspec is given, and use the
pipeline that's used for pathspec mode to get rid of the untracked files
as well.

327864aaf7 worktree prune: improve prune logic when worktree is moved
Automatic detection of worktree relocation by a user (via 'mv', for
instance) was removed by 618244e160 (worktree: stop supporting moving
worktrees manually - 2016-01-22). Prior to that,
.git/worktrees/<tag>/gitdir was updated whenever the worktree was
accessed in order to let the pruning logic know that the worktree was
"active" even if it disappeared for a while (due to being located on
removable media, for instance).

"git worktree move" has come so we don't really need this, but since
it's easy to do, perhaps we could keep supporting manual worktree move
a bit longer. Notice that when a worktree is active, the "index" file
should be updated pretty often in common case. The logic is updated to
check for index mtime to see if the worktree is alive.

The old logic of checking gitdir's mtime is dropped because nobody
updates it anyway. The new corner case is, if the index file does not
exist, we immediately remove the stale worktree. But if the "index"
file does not exist, you may have a bigger problem.

4aa0161e83 shortlog: disallow left-over arguments outside repo
If we are outside a repo and have any arguments left after
option-parsing, `setup_revisions()` will try to do its job and
something like this will happen:

$ git shortlog v2.16.0..
BUG: environment.c:183: git environment hasn't been setup
Aborted (core dumped)

The usage is wrong, but we could obviously handle this better. Note that
commit abe549e179 (shortlog: do not require to run from inside a git
repository, 2008-03-14) explicitly enabled `git shortlog` to run from
outside a repo, since we do not need a repo for parsing data from stdin.

c20bf94abc t9402-git-cvsserver-refs: don't check the stderr of a subshell
Four 'cvs diff' related tests in 't9402-git-cvsserver-refs.sh' fail
when the test script is run with '-x' tracing (and using a shell other
than a Bash version supporting BASH_XTRACEFD).  The reason for those
failures is that the tests check the emptiness of a subshell's stderr,
which includes the trace of commands executed in that subshell as
well, throwing off the emptiness check.

Save the stdout and stderr of the invoked 'cvs' command instead of the
whole subshell, so the latter remains free from tracing output.  (Note
that changing how stdout is saved is only done for the sake of
consistency, it's not necessary for correctness.)

After this change t9402 passes with '-x', even when running with
/bin/sh.

54ce2e9be9 t9400-git-cvsserver-server: don't rely on the output of 'test_cmp'
The test 'cvs update (-p)' redirects and checks 'test_cmp's stdout and
even its stderr.  The commit introducing this test in 6e8937a084
(cvsserver: Add test for update -p, 2008-03-27) doesn't discuss why,
in fact its log message only consists of that subject line.  Anyway,
weird as it is, it kind of made sense due to the way that test was
structured:

After a bit of preparation, this test updates four files via CVS and
checks their contents using 'test_cmp', but it does so in a for loop
iterating over the names of those four files.  Now, the exit status of
a for loop is the exit status of the last command executed in the
loop, meaning that the test can't simply rely on the exit code of
'test_cmp' in the loop's body.  Instead, the test works it around by
relying on the stdout of 'test_cmp' being silent on success and
showing the diff on failure, as it appends the stdout of all four
'test_cmp' invocations to a single file and checks that file's
emptiness after the loop (with 'test -z "$(cat ...)"', no less; there
was no 'test_must_be_empty' back then).  Furthermore, the test
redirects the stderr of those 'test_cmp' invocations to this file,
too: while 'test_cmp' itself doesn't output anything to stderr, the
invoked 'diff' or 'cmp' commands do send their error messages there,
e.g. if they can't open a file because its name was misspelled.

This also makes this test fail when the test script is run with '-x'
tracing (and using a shell other than a Bash version supporting
BASH_XTRACEFD), because 'test_cmp's stderr contains the trace of the
'diff' command executed inside the helper function, throwing off the
subsequent emptiness check.

Stop relying on 'test_cmp's output and instead run 'test_cmp a b ||
return 1' in the for loop in order to make 'test_cmp's error code fail
the test.  Furthermore, add the missing && after the cvs command to
create a && chain in the loop's body.

After this change t9400 passes with '-x', even when running with
/bin/sh.
