completion: mention the oldest version we need to support
This is more of a note for git-completion.bash contributors, not
users. The bash version is from MacOS [1]. Most Linux distros should
be 4.x at this point.
This is another step to help automate git-completion.bash. This option
gives a list of all builtin commands that do use parse_options(),
which supports another hidden option --git-completion-helper. The
output is prepared for easy consumption by git-completion.bash and
separates items by spaces instead of \n

t9902: disable test on the list of merge-strategies under GETTEXT_POISON
The code to learn the list of merge strategies from the output of
"git merge -s help" forces C locale, so that it can notice the
message shown to indicate where the list starts in the output.
However, GETTEXT_POISON build corrupts its output even when run in
the C locale, and we cannot expect this test to succeed.
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.

completion: don't set PARSE_OPT_NOCOMPLETE on --rerere-autoupdate
There is not a strong reason to hide this option, and git-merge already
completes this one. Let's allow to complete this for all commands (and
let git-completion.bash do the suppressing if needed).
This makes --rerere-autoupdate completable for am, cherry-pick and
revert. rebase completion is fixed manually because it's a shell
script and does not benefit from --git-completion-helper.

remote: force completing --mirror= instead of --mirror
"git remote --mirror" is a special case. Technically it is possible to

completion: use __gitcomp_builtin in _git_difftool
Since we can't automatically extract diff options for completion yet,
difftool will take all options from $__git_diff_common_options. This
brings _a lot_ more completable options to difftool.
--ignore-submodules is added to $__git_diff_common_options to avoid
regression in difftool. But it's a good thing anyway even for other
diff commands.

to get the list of completable options. The call will be made only
once and cached to avoid performance issues, especially on Windows.
__gitcomp_builtin() allows callers to change its output a bit by adding
some more options, or removing some.
- Current --git-completion-helper for example does not output --no-foo
form, this has to be added manually by __gitcomp_builtin() callers
when necessary
- Some options from --git-completion-helper should only be available in
certain conditions (e.g. --continue and friends). __gitcomp_builtin()
callers can remove them if the conditions are not met.

There are various git subcommands (among them, clone) which don't set up
the repository (that is, they lack RUN_SETUP or RUN_SETUP_GENTLY) but
end up needing to have information about the hash algorithm in use.
Because the hash algorithm is part of struct repository and it's only
initialized in repository setup, we can end up dereferencing a NULL
pointer in some cases if we call one of these subcommands and look up
the empty blob or empty tree values.
A "git clone" of a project that has two paths that differ only in
case suffers from this if it is run on a case insensitive platform.
When the command attempts to check out one of these two paths after
checking out the other one, the checkout codepath needs to see if
the version that is already on the filesystem (which should not
happen if the FS were case sensitive) is dirty, and it needs to
exercise the hashing code at that point.
In the future, we can add a command line option for this or read it
from the configuration, but until we're ready to expose that
functionality to the user, simply initialize the repository
structure to use the current hash algorithm, SHA-1.

add--interactive: ignore submodule changes except HEAD
For 'add -i' and 'add -p', the only action we can take on a dirty
submodule entry is update the index with a new value from its HEAD. The
content changes inside (from its own index, untracked files...) do not
matter, at least until 'git add -i' learns about launching a new
interactive add session inside a submodule.
Ignore all other submodules changes except HEAD. This reduces the number
of entries the user has to check through in 'git add -i', and the number
of 'no' they have to answer to 'git add -p' when dirty submodules are
present.

A reader of this documentation may be misled into thinking that

as opposed to:

mingw: handle GITPERLLIB in t0021 in a Windows-compatible way
Git's assumption that all path lists are colon-separated is not only
wrong on Windows, it is not even an assumption that is compatible with
POSIX.
In the interest of time, let's not try to fix this properly but simply
work around the obvious breakage on Windows, where the MSYS2 Bash used
by Git for Windows to interpret the Git's Unix shell scripts will
automagically convert path lists in the environment to
semicolon-separated lists of Windows paths (with drive letter and the
corresponding colon and all that jazz).
In other words, we simply look whether there is a semicolon in
GITPERLLIB and split by semicolons if found instead of colons. This is
not fool-proof, of course, as the path list could consist of a single
path. But that is not the case in Git for Windows' test suite, there are
always two paths in GITPERLLIB.
