a577d2f1a9 builtin/config: stop printing full usage on misuse
When invoking git-config(1) with a wrong set of arguments we end up
calling `usage_builtin_config()` after printing an error message that
says what was wrong. As that function ends up printing the full list of
options, which is quite long, the actual error message will be buried by
a wall of text. This makes it really hard to figure out what exactly
caused the error.

Furthermore, now that we have recently introduced subcommands, the usage
information may actually be misleading as we unconditionally print
options of the subcommand-less mode.

Fix both of these issues by just not printing the options at all
anymore. Instead, we call `usage()` that makes us report in a single
line what has gone wrong. This should be way more discoverable for our
users and addresses the inconsistency.

Furthermore, this change allow us to inline the options into the
respective functions that use them to parse the command line.

Until now, `git config -h` would have printed help for the old-style

preferable to instead display the subcommand help.

that git-config(1)'s synopsis and `git config -h` match.

14970509c6 builtin/config: introduce "list" subcommand
While git-config(1) has several modes, those modes are not exposed with
subcommands but instead by specifying action flags like `--unset` or
`--list`. This user interface is not really in line with how our more
modern commands work, where it is a lot more customary to say e.g. `git
remote list`. Furthermore, to add to the confusion, git-config(1) also
allows the user to request modes implicitly by just specifying the
correct number of arguments. Thus, `git config foo.bar` will retrieve
the value of "foo.bar" while `git config foo.bar baz` will set it to
"baz".

Overall, this makes for a confusing interface that could really use a
makeover. It hurts discoverability of what you can do with git-config(1)
and is comparatively easy to get wrong. Converting the command to have
subcommands instead would go a long way to help address these issues.

One concern in this context is backwards compatibility. Luckily, we can
introduce subcommands without breaking backwards compatibility at all.
This is because all the implicit modes of git-config(1) require that the
first argument is a properly formatted config key. And as config keys
_must_ have a dot in their name, any value without a dot would have been
discarded by git-config(1) previous to this change. Thus, given that
none of the subcommands do have a dot, they are unambiguous.

Introduce the first such new subcommand, which is "git config list". To
retain backwards compatibility we only conditionally use subcommands and
will fall back to the old syntax in case no subcommand was detected.
This should help to transition to the new-style syntax until we
eventually deprecate and remove the old-style syntax.

Note that the way we handle this we're duplicating some functionality
across old and new syntax. While this isn't pretty, it helps us to
ensure that there really is no change in behaviour for the old syntax.

Amend tests such that we run them both with old and new style syntax.
As tests are now run twice, state from the first run may be still be
around in the second run and thus cause tests to fail. Add cleanup logic
as required to fix such tests.

daa3325024 builtin/config: use OPT_CMDMODE() to specify modes
The git-config(1) command has various different modes which are
accessible via e.g. `--get-urlmatch` or `--unset-all`. These modes are
declared with `OPT_BIT()`, which causes two minor issues:

  - The respective modes also have a negated form `--no-get-urlmatch`,
    which is unintended.

  - We have to manually handle exclusiveness of the modes.

Switch these options to instead use `OPT_CMDMODE()`, which is made
exactly for this usecase. Remove the now-unneeded check that only a
single mode is given, which is now handled by the parse-options
interface.

While at it, format optional placeholders for arguments to conform to
our style guidelines by using `[<placeholder>]`.

7b97dfe47b color: add support for 12-bit RGB colors
RGB color parsing currently supports 24-bit values in the form #RRGGBB.

As in Cascading Style Sheets (CSS [1]), also allow to specify an RGB color
using only three digits with #RGB.

In this shortened form, each of the digits is – again, as in CSS –
duplicated to convert the color to 24 bits, e.g. #f1b specifies the same
color as #ff11bb.

In color.h, remove the '0x' prefix in the example to match the actual
syntax.

058b8dc2c2 t4046: avoid continue in &&-chain for zsh
zsh has a bug in which the keyword "continue" within an &&-chain is not
effective and the code following it is executed nonetheless.
Fortunately, this bug has been fixed upstream in 12e5db145 ("51608:
Don't execute commands after "continue &&"", 2023-03-29).  However, zsh
releases very infrequently, so it is not present in a stable release
yet.

That, combined with the fact that almost all zsh users get their shell
from their OS vendor, means that it will likely be a long time before
this problem is fixed for most users.  We have other workarounds in
place for FreeBSD ash and dash, so it shouldn't be too difficult to add
one here, either.

Replace the existing code with a test and if-block, which comes only at
the cost of an additional indentation, and leaves the code a little more
idiomatic anyway.

c75662bfc9 maintenance: running maintenance should not stop on errors
In https://github.com/microsoft/git/issues/623, it was reported that
maintenance stops on a missing repository, omitting the remaining
repositories that were scheduled for maintenance.

This is undesirable, as it should be a best effort type of operation.

It should still fail due to the missing repository, of course, but not
leave the non-missing repositories in unmaintained shapes.

Let's use `for-each-repo`'s shiny new `--keep-going` option that we just
introduced for that very purpose.

12c2ee5fbd for-each-repo: optionally keep going on an error
In https://github.com/microsoft/git/issues/623, it was reported that
the regularly scheduled maintenance stops if one repo in the middle of
the list was found to be missing.

This is undesirable, and points out a gap in the design of `git
for-each-repo`: We need a mode where that command does not stop on an
error, but continues to try running the specified command with the other
repositories.

Imitating the `--keep-going` option of GNU make, this commit teaches
`for-each-repo` the same trick: to continue with the operation on all
the remaining repositories in case there was a problem with one
repository, still setting the exit code to indicate an error occurred.

ce36894509 format-patch: "--rfc=-(WIP)" appends to produce [PATCH (WIP)]
In the previous step, the "--rfc" option of "format-patch" learned
to take an optional string value to prepend to the subject prefix,
so that --rfc=WIP can give "[WIP PATCH]".

There may be cases in which the extra string wants to come after the
subject prefix.  Extend the mechanism to allow "--rfc=-(WIP)" [*] to
signal that the extra string is to be appended instead of getting
prepended, resulting in "[PATCH (WIP)]".

In the documentation, discourage (ab)using "--rfc=-RFC" to say
"[PATCH RFC]" just to be different, when "[RFC PATCH]" is the norm.

ce48fb2eab format-patch: allow --rfc to optionally take a value, like --rfc=WIP
With the "--rfc" option, we can tweak the "[PATCH]" (or whatever
string specified with the "--subject-prefix" option, instead of
"PATCH") that we prefix the title of the commit with into "[RFC
PATCH]", but some projects may want "[rfc PATCH]".  Adding a new
option, e.g., "--rfc-lowercase", to support such need every time
somebody wants to use different strings would lead to insanity of
accumulating unbounded number of such options.

Allow an optional value specified for the option, so that users can
use "--rfc=rfc" (think of "--rfc" without value as a short-hand for
"--rfc=RFC") if they wanted to.

This can of course be (ab)used to make the prefix "[WIP PATCH]" by
passing "--rfc=WIP".  Passing an empty string, i.e., "--rfc=", is
the same as "--no-rfc" to override an option given earlier on the
same command line.

Plug a leak we have since 5a76aff1a6 (add: convert to use
parse_pathspec, 2013-07-14).

This leak can be triggered with:
    $ git add -p anything

Fixing this leak allows us to mark as leak-free the following tests:

    + t7514-commit-patch.sh

Mark them with "TEST_PASSES_SANITIZE_LEAK=true" to notice and fix
promply any new leak that may be introduced and triggered by them in the
future.

5fb7686409 stash: fix "--staged" with binary files
"git stash --staged" errors out when given binary files, after saving the
stash.

This behaviour dates back to the addition of the feature in 41a28eb6c1
(stash: implement '--staged' option for 'push' and 'save', 2021-10-18).
Adding the "--binary" option of "diff-tree" fixes this. The "diff-tree" call
in stash_patch() also omits "--binary", but that is fine since binary files
cannot be selected interactively.

cadcf58085 format-patch: ensure that --rfc and -k are mutually exclusive
Fix a bug that allows the "--rfc" and "-k" options to be specified together
when "git format-patch" is executed, which was introduced in the commit
e0d7db7423 ("format-patch: --rfc honors what --subject-prefix sets").

Add a couple of additional tests to t4014, to cover additional cases of
the mutual exclusivity between different "git format-patch" options.

a6c2654f83 rebase -m: fix --signoff with conflicts
When rebasing with "--signoff" the commit created by "rebase --continue"
after resolving conflicts or editing a commit fails to add the
"Signed-off-by:" trailer. This happens because the message from the
original commit is reused instead of the one that would have been used
if the sequencer had not stopped for the user interaction. The correct
message is stored in ctx->message and so with a couple of exceptions
this is written to rebase_path_message() when stopping for user
interaction instead. The exceptions are (i) "fixup" and "squash"
commands where the file is written by error_failed_squash() and (ii)
"edit" commands that are fast-forwarded where the original message is
still reused. The latter is safe because "--signoff" will never
fast-forward.

Note this introduces a change in behavior as the message file now
contains conflict comments. This is safe because commit_staged_changes()
passes an explicit cleanup flag when not editing the message and when
the message is being edited it will be cleaned up automatically. This
means user now sees the same message comments in editor with "rebase
--continue" as they would if they ran "git commit" themselves before
continuing the rebase. It also matches the behavior of "git
cherry-pick", "git merge" etc. which all list the files with merge
conflicts.

The tests are extended to check that all commits made after continuing a
rebase have a "Signed-off-by:" trailer. Sadly there are a couple of
leaks in apply.c which I've not been able to track down that mean this
test file is no-longer leak free when testing "git rebase --apply
--signoff" with conflicts.

0c47355790 repository: drop initialize_the_repository()
Now that we have dropped `the_index`, `initialize_the_repository()`
doesn't really do a lot anymore except for setting up the pointer for
`the_repository` and then calling `initialize_repository()`. The former
can be replaced by statically initializing the pointer though, which
basically makes this function moot.

Convert callers to instead call `initialize_repository(the_repository)`
and drop `initialize_thee_repository()`.

93e2ae1c95 midx: disable replace objects
We observed a series of clone failures arose in a specific set of
repositories after we fully enabled the MIDX bitmap feature within our
Codebase service. These failures were accompanied with error messages
such as:

    Cloning into bare repository 'clone.git'...
    remote: Enumerating objects: 8, done.
    remote: Total 8 (delta 0), reused 0 (delta 0), pack-reused 8 (from 1)
    Receiving objects: 100% (8/8), done.
    fatal: did not receive expected object ...
    fatal: fetch-pack: invalid index-pack output

Temporarily disabling the MIDX feature eliminated the reported issues.
After some investigation we found that all repositories experiencing
failures contain replace references, which seem to be improperly
acknowledged by the MIDX bitmap generation logic.

A more thorough explanation about the root cause from Taylor Blau says:

Indeed, the pack-bitmap-write machinery does not itself call
disable_replace_refs(). So when it generates a reachability bitmap, it
is doing so with the replace refs in mind. You can see that this is
indeed the cause of the problem by looking at the output of an
instrumented version of Git that indicates what bits are being set
during the bitmap generation phase.

With replace refs (incorrectly) enabled, we get:

    [2, 4, 6, 8, 13, 3, 6, 7, 3, 4, 6, 8]

and doing the same after calling disable_replace_refs(), we instead get:

    [2, 5, 6, 13, 3, 6, 7, 3, 4, 6, 8]

Single pack bitmaps are unaffected by this issue because we generate
them from within pack-objects, which does call disable_replace_refs().

This patch updates the MIDX logic to disable replace objects within the
multi-pack-index builtin, and a test showing a clone (which would fail
with MIDX bitmap) is added to demonstrate the bug.
