Create a stress test to hammer on the fsmonitor daemon.
Create a client-side thread pool of n threads and have
each of them make m requests as fast as they can.
We do not currently inspect the contents of the response.
We're only interested in placing a heavy request load on
the daemon.
This test is useful for interactive testing and various
experimentation. For example, to place additional load
on the daemon while another test is running. We currently
do not have a test script that actually uses this helper.
We might add such a test in the future.

Create some test repos with UTF8 characters in the pathname of the
root directory and verify that the builtin FSMonitor can watch them.
This test is mainly for Windows where we need to avoid `*A()`
routines.

Teach FSMonitor daemon on Windows to recognize shortname paths as
aliases of normal longname paths. FSMonitor clients, such as `git
status`, should receive the longname spelling of changed files (when
possible).
Sometimes we receive FS events using the shortname, such as when a CMD
shell runs "RENAME GIT~1 FOO" or "RMDIR GIT~1". The FS notification
arrives using whatever combination of long and shortnames were used by
the other process. (Shortnames do seem to be case normalized,
however.)
Use Windows GetLongPathNameW() to try to map the pathname spelling in
the notification event into the normalized longname spelling. (This
can fail if the file/directory is deleted, moved, or renamed, because
we are asking the FS for the mapping in response to the event and
after it has already happened, but we try.)
Special case the shortname spelling of ".git" to avoid under-reporting
these events.

The "FUNNYNAMES" test prerequisite passes on Cygwin, as the Cygwin
file system interface has a workaround for the underlying operating
system's lack of support for tabs, newlines or quotes. However, it does
not add support for backslash, which is treated as a directory
separator, meaning one of the tests added by 48803821b1 ("completion:
handle unusual characters for sparse-checkout", 2022-02-07) will fail on
Cygwin.
To avoid this failure while still getting maximal test coverage, split
that test into two: test handling of paths that include tabs on anything
that has the FUNNYNAMES prerequisite, but skip testing handling of paths
that include backslashes unless both FUNNYNAMES is set and the system is
not Cygwin.
It might be nice to have more granularity than "FUNNYNAMES" and its
sibling "FUNNIERNAMES" provide, so that tests could be run based on
specific individual characters supported by the file system being
tested, but that seems like it would make the prerequisite checks in
this area much more verbose for very little gain.

The ls-tree documentation had never been updated after it learned to
interact with submodules to explicitly mention them. The initial
support was added in f35a6d3bce (Teach core object handling functions
about gitlinks, 2007-04-09). E.g. the discussion of --long added in
f35a6d3bce (Teach core object handling functions about gitlinks,
2007-04-09) didn't explicitly mention them.
But this documentation added in 455923e0a1 (ls-tree: introduce
"--format" option, 2022-03-23) had no such excuse, and was actively
misleading by providing an exhaustive but incomplete list of object

Commit 455923e0a1 ("ls-tree: introduce "--format" option", 2022-03-23)
introduced `--format` and the various placeholders it can take, such as
%(objectname) and %(objectsize).
At some point when that patch was being developed, those placeholders
had shorter names, e.g., %(name) and %(size), which can be seen in the
commit message of 455923e0a1. One instance of "%(size:padded)" also
managed to enter the documentation in the final version of the patch.
Correct it to "%(objectsize:padded)".

Under certain (not quite easy to force, apparently) circumstances, a Git
process that just warned about the deprecated config setting will spawn
another Git process that then _also_ warns about that config setting.
Let's try to tone that down by setting an environment variable that
indicates that this process and all of its children no longer need to
tell the user about this deprecation.
Note: This patch does not help in situations where, say, scripts call
Git multiple times and each of those times Git prints this deprecation
notice. It is unclear whether we can do anything about this because
those Git processes would have to signal to their _parent_ process that
the advice was already provided.

Asciidoc renders `--` as em-dash. This is not appropriate for command

Fix git-credential-cache--daemon and git-fsmonitor--daemon. The latter

turned this up.
Manually inspecting the other Documentation/git-*--*.txt files turned up
the issue in git-credential-cache--daemon.

Fix a regression in my dad9cd7d51 (Makefile: move ".SUFFIXES" rule to
shared.mak, 2022-03-03). As explained in the GNU make documentation
for the $* variable, available at:
info make --index-search='$*'
This rule relied on ".texi" being in the default list of suffixes, as
seen at:
make -f/dev/null -p | grep -v -e ^# -e ^$|grep -F .SUFFIXES
The documentation explains what was going on here:
In an explicit rule, there is no stem; so '$*' cannot be determined
in that way. Instead, if the target name ends with a recognized
suffix (*note Old-Fashioned Suffix Rules: Suffix Rules.), '$*' is
set to the target name minus the suffix. For example, if the
target name is 'foo.c', then '$*' is set to 'foo', since '.c' is a
suffix. GNU 'make' does this bizarre thing only for compatibility
with other implementations of 'make'. You should generally avoid
using '$*' except in implicit rules or static pattern rules.
If the target name in an explicit rule does not end with a
recognized suffix, '$*' is set to the empty string for that rule.
I.e. this rule added back in 5cefc33bff (Documentation: add
gitman.info target, 2007-12-10) was resolving gitman.texi from
gitman.info. We can instead just use the more obvious $< variable
referring to the prerequisite.
This was the only use of $* in our Makefiles in an explicit rule, the
three remaining ones are all implicit rules, and therefore didn't
depend on the ".SUFFIXES" list.

In 9c4d58ff2c (ls-tree: split up "fast path" callbacks, 2022-03-23), a
refactoring of the various read_tree_at() callbacks caused us to
unconditionally recurse into directories if `-l` (long format) was
passed on the command line, regardless of whether or not we also pass
the `-r` (recursive) flag.
Fix this by making show_tree_long() return the value of `recurse`,
rather than always returning 1. This value is interpreted by
read_tree_at() to be a signal on whether or not to recurse.

One trigger is an unexpectedly difficult to resolve conflict, as

In e3f7e01b50 (Revert "editor: save and reset terminal after calling
EDITOR", 2021-11-22), we reverted the commit wholesale where the
terminal state would be saved and restored before/after calling an
editor.
The reverted commit was intended to fix a problem with Windows Terminal
where simply calling `vi` would cause problems afterwards.
To fix the problem addressed by the revert, but _still_ keep the problem
with Windows Terminal fixed, let's revert the revert, with a twist: we
restrict the save/restore _specifically_ to the case where `vi` (or
`vim`) is called, and do not do the same for any other editor.
This should still catch the majority of the cases, and will bridge the
time until the original patch is re-done in a way that addresses all
concerns.

The `xutftowcs_path` function canonicalizes absolute paths using GetFullPathNameW.
This canonicalization may change the length of the string (e.g. getting rid of \.\),
which breaks callers that pass the template string in a strbuf and expect the
length of the string to remain the same.
In my particular case, the tmp-objdir code is passing a strbuf to mkdtemp and is
breaking since the strbuf.len is no longer synchronized with strlen(strbuf.buf).
