A recent update to contrib/completion/git-completion.bash causes bash to fail
auto complete custom commands that are wrapped with __git_func_wrap. Declaring
__git_cmd_idx=0 inside __git_func_wrap resolves the issue.

With the introduction of the $__git_cmd_idx variable in e94fb44042
(git-completion.bash: pass $__git_subcommand_idx from __git_main(),
2021-03-24), completion functions were able to know the index at which
the git command is listed, allowing them to skip options that are given
to the underlying git itself, not the corresponding command (e.g.
`-C asdf` in `git -C asdf branch`).
While most of the changes here are self-explanatory, some bear further
explanation.
For the __git_find_on_cmdline() and __git_find_last_on_cmdline() pair of
functions, these functions are only ever called in the context of a git
command completion function. These functions will only care about words
after the command so we can safely ignore the words before this.
For _git_worktree(), this change is technically a no-op (once the
__git_find_last_on_cmdline change is also applied). It was in poor style
to have hard-coded on the index right after `worktree`. In case
`git worktree` were to ever learn to accept options, the current
situation would be inflexible.

In e94fb44042 (git-completion.bash: pass $__git_subcommand_idx from
__git_main(), 2021-03-24), the $__git_subcommand_idx variable was
introduced. Naming it after the index of the subcommand is needlessly
confusing as, when this variable is used, it is in the completion
functions for commands (e.g. _git_remote()) where for `git remote add`,
the `remote` is referred to as the command and `add` is referred to as
the subcommand.
Rename this variable so that it's obvious it's about git commands. While
we're at it, shorten up its name so that it's still readable without
being a handful to type.

In e94fb44042 (git-completion.bash: pass $__git_subcommand_idx from
__git_main(), 2021-03-24), a line was introduced which contained
multiple statements. This is difficult to read so break it into multiple
lines.
While we're at it, follow this convention for the rest of the
__git_main() and break up lines that contain multiple statements.

The completion for 'git stash' has not changed in a major way since it
was converted from shell script to builtin. Now that it's a builtin, we
can take advantage of the groundwork laid out by parse-options and use
the generated options.
Rewrite _git_stash() to take use __gitcomp_builtin() to generate
completions for subcommands.
The main `git stash` command does not take any arguments directly. If no
subcommand is given, it automatically defaults to `git stash push`. This
means that we can simplify the logic for when no subcommands have been
given yet. We only have to offer subcommand completions when we're
completing a non-option after "stash".
One area that this patch could improve upon is that the `git stash list`
command accepts log-options. It would be nice if the completion for this
were unified with that of _git_log() and _git_show() which would allow
completions to be provided for options such as `--pretty` but that is
outside the scope of this patch.

Many completion functions perform hardcoded comparisons with $cword.
This fails in the case where the main git command is given arguments
(e.g. `git -C . bundle<TAB>` would fail to complete its subcommands).
Even _git_worktree(), which uses __git_find_on_cmdline(), could still
fail. With something like `git -C add worktree move<TAB>`, the
subcommand would be incorrectly identified as "add" instead of "move".
Assign $__git_subcommand_idx in __git_main(), where the git subcommand
is actually found and the corresponding completion function is called.
Use this variable to replace hardcoded comparisons with $cword.

Disable the recent mergetool's hideresolved feature by default for
backward compatibility and safety.
* jn/mergetool-hideresolved-is-optional:
doc: describe mergetool configuration in git-mergetool(1)
mergetool: do not enable hideResolved by default
In particular, this describes mergetool.hideResolved, which can help
users discover this setting (either because it may be useful to them
or in order to understand mergetool's behavior if they have forgotten
setting it in the past).

When 98ea309b3f (mergetool: add hideResolved configuration,
2021-02-09) introduced the mergetool.hideResolved setting to reduce
the clutter in viewing non-conflicted sections of files in a
mergetool, it enabled it by default, explaining:
No adverse effects were noted in a small survey of popular mergetools[1]
so this behavior defaults to `true`.
In practice, alas, adverse effects do appear. A few issues:
1. No indication is shown in the UI that the base, local, and remote
versions shown have been modified by additional resolution. This
is inherent in the design: the idea of mergetool.hideResolved is to
convince a mergetool that expects pristine local, base, and remote
files to show partially resolved verisons of those files instead;
there is no additional source of information accessible to the
mergetool to see where the resolution has happened.
(By contrast, a mergetool generating the partial resolution from
conflict markers for itself would be able to hilight the resolved
sections with a different color.)
A user accustomed to seeing the files without partial resolution
gets no indication that this behavior has changed when they upgrade
Git.
2. If the computed merge did not line up the files correctly (for
example due to repeated sections in the file), the partially
resolved files can be misleading and do not have enough information
to reconstruct what happened and compute the correct merge result.
3. Resolving a conflict can involve information beyond the textual
conflict. For example, if the local and remote versions added
overlapping functionality in different ways, seeing the full
unresolved versions of each alongside the base gives information
about each side's intent that makes it possible to come up with a
resolution that combines those two intents. By contrast, when
starting with partially resolved versions of those files, one can
produce a subtly wrong resolution that includes redundant extra
code added by one side that is not needed in the approach taken
on the other.
All that said, a user wanting to focus on textual conflicts with
reduced clutter can still benefit from mergetool.hideResolved=true as
a way to deemphasize sections of the code that resolve cleanly without
requiring any changes to the invoked mergetool. The caveats described
above are reduced when the user has explicitly turned this on, because
then the user is aware of them.
Flip the default to 'false'.

The code to fsck objects received across multiple packs during a
single git fetch session has been broken when the packfile URI
feature was in use. A workaround has been added by disabling the
codepath to avoid keeping a packfile that is too small.
* jt/transfer-fsck-across-packs-fix:
fetch-pack: do not mix --pack_header and packfile uri
When fetching (as opposed to cloning) from a repository with packfile
URIs enabled, an error like this may occur:
fatal: pack has bad object at offset 12: unknown object type 5
fatal: finish_http_pack_request gave result -1
fatal: fetch-pack: expected keep then TAB at start of http-fetch output
This bug was introduced in b664e9ffa1 ("fetch-pack: with packfile URIs,
use index-pack arg", 2021-02-22), when the index-pack args used when
processing the inline packfile of a fetch response and when processing
packfile URIs were unified.
This bug happens because fetch, by default, partially reads (and
consumes) the header of the inline packfile to determine if it should
store the downloaded objects as a packfile or loose objects, and thus
passes --pack_header=<...> to index-pack to inform it that some bytes
are missing. However, when it subsequently fetches the additional
packfiles linked by URIs, it reuses the same index-pack arguments, thus
wrongly passing --index-pack-arg=--pack_header=<...> when no bytes are
missing.
This does not happen when cloning because "git clone" always passes
do_keep, which instructs the fetch mechanism to always retain the
packfile, eliminating the need to read the header.
There are a few ways to fix this, including filtering out pack_header
arguments when downloading the additional packfiles, but I decided to
stick to always using index-pack throughout when packfile URIs are
present - thus, Git no longer needs to read the bytes, and no longer
needs --pack_header here.

There were some early changes in the 2.31 cycle to optimize some setup
in diffcore-rename.c[1], some later changes to measure performance[2],
and finally some significant changes to improve rename detection
performance. The final one was merged with the note
Performance optimization work on the rename detection continues.
That works for the commit log, but feels misleading as a release note
since all the changes were within one cycle. Simplify this to just
Performance improvements for rename detection.
The former wording could be seen as hinting that more performance
improvements will come in 2.32, which is true, but we can just cover
those in the 2.32 release notes when the time comes.
