The completion code can be told to use a particular completion for
aliases that shell out by using ': git <cmd> ;' as the first command of
the alias. This only works if <cmd> and the semicolon are separated by a
space, since if the space is missing __git_aliased_command returns (for
example) 'checkout;' instead of just 'checkout', and then
__git_complete_command fails to find a completion for 'checkout;'.
The examples have that space but it's not clear if it's just for
style or if it's mandatory. Explicitly mention it.

In the previous commit, we added support for completing configured
trailer tokens in 'git commit --trailer'.
Make the implementation more robust by:
- using '__git' instead of plain 'git', as the rest of the completion
script does
- using a stricter pattern for --get-regexp to avoid false hits
- using 'cut' and 'rev' instead of 'awk' to account for tokens including
dots.

This test was introduced by commit 0c164ae7a ("rebase -i: add another
reword test", 2021-08-20). I didn't quite get what it was meant to do,
so here's an explanation from Phillip:
The purpose of the test is to ensure that
(i) There are no uncommitted changes when the editor runs. i.e., we
commit without running the editor and then reword by amending
that commit. This ensures that we have the same user experience
whether or not the commit was fast-forwarded [1].
(ii) That the todo list is re-read after the commit has been reworded.
This is to allow the user to update the todo list while the rebase
is paused for editing the commit message.

`git diff-index` may return incorrect deleted entries when fsmonitor
is used in a repository with git submodules. This can be observed on
Mac machines, but it can affect all other supported platforms too.
If fsmonitor is used, `stat *st` is not initialized if cache_entry has
CE_FSMONITOR_VALID set. But, there are three call sites that rely on stat
afterwards, which can result in incorrect results.
This change partially reverts commit 4f3d6d02 (fsmonitor: skip lstat

When running in the Windows Subsystem for Linux (WSL), it is usually
necessary to use the Git Credential Manager for authentication when
performing the background fetches.
This requires interoperability between the Windows Subsystem for Linux
and the Windows host to work, which uses so-called vsocks, i.e. sockets
intended for communcations between virtual machines and the host they
are running on.
However, when Git is configured to run background maintenance via
`systemd`, the address families available to those maintenance processes
are restricted, and did not include `AF_VSOCK`. This leads to problems
e.g. when a background fetch tries to access github.com:
systemd[437]: Starting Optimize Git repositories data...
git[747387]: WSL (747387) ERROR: UtilBindVsockAnyPort:285: socket failed 97
git[747381]: fatal: could not read Username for 'https://github.com': No such device or address
git[747381]: error: failed to prefetch remotes
git[747381]: error: task 'prefetch' failed
systemd[437]: git-maintenance@hourly.service: Main process exited, code=exited, status=1/FAILURE
systemd[437]: git-maintenance@hourly.service: Failed with result 'exit-code'.
systemd[437]: Failed to start Optimize Git repositories data.
Address this (pun intended) by adding the `AF_VSOCK` address family to
the allow list.

Previously these fields in the trailer_info struct were of type "const
char *" and pointed to positions in the input string directly (to the
start and end positions of the trailer block).
Use offsets to make the intended usage less ambiguous. We only need to

function to take a pointer to the input.

Do not use *_DEFAULT as a suffix to the enums, because the word
"default" is overloaded. The following are two examples of the ambiguity
of the word "default":
(1) "Default" can mean using the "default" values that are hardcoded
in trailer.c as
default_conf_info.where = WHERE_END;
default_conf_info.if_exists = EXISTS_ADD_IF_DIFFERENT_NEIGHBOR;
default_conf_info.if_missing = MISSING_ADD;
in ensure_configured(). These values are referred to as "the
default" in the docs for interpret-trailers. These defaults are used
if no "trailer.*" configurations are defined.
(2) "Default" can also mean the "trailer.*" configurations themselves,
because these configurations are used by "default" (ahead of the
hardcoded defaults in (1)) if no command line arguments are
provided. This concept of defaulting back to the configurations was
introduced in 0ea5292e6b (interpret-trailers: add options for
actions, 2017-08-01).
In addition, the corresponding *_DEFAULT values are chosen when the user
provides the "--no-where", "--no-if-exists", or "--no-if-missing" flags
on the command line. These "--no-*" flags are used to clear previously
provided flags of the form "--where", "--if-exists", and "--if-missing".
Using these "--no-*" flags undoes the specifying of these flags (if
any), so using the word "UNSPECIFIED" is more natural here.
So instead of using "*_DEFAULT", use "*_UNSPECIFIED" because this
signals to the reader that the *_UNSPECIFIED value by itself carries no
meaning (it's a zero value and by itself does not "default" to anything,
necessitating the need to have some other way of getting to a useful
value).

Currently, find_patch_start only finds the start of the patch part of
the input (by looking at the "---" divider) for cases where the
"--no-divider" flag has not been provided. If the user provides this
flag, we do not rely on find_patch_start at all and just call strlen()
directly on the input.
Instead, make find_patch_start aware of "--no-divider" and make it
handle that case as well. This means we no longer need to call strlen at
all and can just rely on the existing code in find_patch_start. By
forcing callers to consider this important option, we avoid the kind of
mistake described in be3d654343 (commit: pass --no-divider to
interpret-trailers, 2023-06-17).
This patch will make unit testing a bit more pleasant in this area in
the future when we adopt a unit testing framework, because we would not
have to test multiple functions to check how finding the start of a
patch part works (we would only need to test find_patch_start).

Currently, process_input_file does three things:

(2) print text before the trailers, and
(3) calculate the position of the input where the trailers end.
Rename this function to parse_trailers(), and make it only do
(1). The caller of this function, process_trailers, becomes responsible
for (2) and (3). These items belong inside process_trailers because they
are both concerned with printing the surrounding text around
trailers (which is already one of the immediate concerns of
process_trailers).

When `git switch --track ` is to be completed, only remote refs are
eligible because that is what the `--track` option targets.
And when the short-hand `-t` is used instead, the same _should_ happen.
Let's make it so.
Note that the bug exists both in the completions of `switch` and
`completion`, even if it manifests in slightly different ways: While
the completion of `git switch -t ` will not even look at remote refs,
the completion of `git checkout -t ` will look at both remote _and_
local refs. Both should look only at remote refs.

When rebasing commands are moved from the todo list in "git-rebase-todo"
to the "done" file (which is used by "git status" to show the recently
executed commands) just before they are executed. This means that if a
command fails because it would overwrite an untracked file it has to be
added back into the todo list before the rebase stops for the user to
fix the problem.
Unfortunately when a failed command is added back into the todo list the
command preceding it is erroneously appended to the "done" file. This
means that when rebase stops after "pick B" fails the "done" file
contains
pick A
pick B
pick A
instead of
pick A
pick B
This happens because save_todo() updates the "done" file with the
previous command whenever "git-rebase-todo" is updated. When we add the
failed pick back into "git-rebase-todo" we do not want to update
"done". Fix this by adding a "reschedule" parameter to save_todo() which
prevents the "done" file from being updated when adding a failed command
back into the "git-rebase-todo" file. A couple of the existing tests are
modified to improve their coverage as none of them trigger this bug or
check the "done" file.
