In the previous commit, we ensured that grouping is used for the build
in all jobs, and this allows us to piggy-back onto the `group` function
to transmogrify the output.
Note: If `set -o pipefail` was available, we could do this in a little
more elegant way. But since some of the steps are run using `dash`, we
have to do a little `{ ...; echo $? >exit.status; } | ...` dance.

In rare cases[1], wait_or_whine() cannot determine a child process's
status (and will return -1 in this case). This can cause Git to issue
trace2 child_exit events despite the fact that the child may still be
running. In pathological cases, we've seen > 80 million exit events in
our trace logs for a single child process.
Fix this by only issuing trace2 events in finish_command_in_signal() if
we get a value other than -1 from wait_or_whine(). This can lead to
missing child_exit events in such a case, but that is preferable to
duplicating events on a scale that threatens to fill the user's
filesystem with invalid trace logs.
[1]: This can happen when:
* waitpid() returns -1 and errno != EINTR
* waitpid() returns an invalid PID
* the status set by waitpid() has neither the WIFEXITED() nor
WIFSIGNALED() flags

Fix a regression reported[1] against f443246b9f (commit: convert
{pre-commit,prepare-commit-msg} hook to hook.h, 2021-12-22): Due to
using the run_process_parallel() API in the earlier 96e7225b31 (hook:
add 'run' subcommand, 2021-12-22) we'd capture the hook's stderr and
stdout, and thus lose the connection to the TTY in the case of
e.g. the "pre-commit" hook.
As a preceding commit notes GNU parallel's similar --ungroup option
also has it emit output faster. While we're unlikely to have hooks
that emit truly massive amounts of output (or where the performance
thereof matters) it's still informative to measure the overhead. In a
similar "seq" test we're now ~30% faster:

Extend the parallel execution API added in c553c72eed (run-command:
add an asynchronous parallel child processor, 2015-12-15) to support a
mode where the stdout and stderr of the processes isn't captured and
output in a deterministic order, instead we'll leave it to the kernel
and stdio to sort it out.
This gives the API same functionality as GNU parallel's --ungroup
option. As we'll see in a subsequent commit the main reason to want
this is to support stdout and stderr being connected to the TTY in the
case of jobs=1, demonstrated here with GNU parallel:
$ parallel --ungroup 'test -t {} && echo TTY || echo NTTY' ::: 1 2
TTY
TTY
$ parallel 'test -t {} && echo TTY || echo NTTY' ::: 1 2
NTTY
NTTY
Another is as GNU parallel's documentation notes a potential for
optimization. As demonstrated in next commit our results with "git
hook run" will be similar, but generally speaking this shows that if
you want to run processes in parallel where the exact order isn't
important this can be a lot faster:
$ hyperfine -r 3 -L o ,--ungroup 'parallel {o} seq ::: 10000000 >/dev/null '
Benchmark 1: parallel seq ::: 10000000 >/dev/null
Time (mean ± σ): 220.2 ms ± 9.3 ms [User: 124.9 ms, System: 96.1 ms]

Benchmark 2: parallel --ungroup seq ::: 10000000 >/dev/null
Time (mean ± σ): 154.7 ms ± 0.9 ms [User: 136.2 ms, System: 25.1 ms]
Range (min … max): 153.9 ms … 155.7 ms 3 runs
Summary
'parallel --ungroup seq ::: 10000000 >/dev/null ' ran
1.42 ± 0.06 times faster than 'parallel seq ::: 10000000 >/dev/null '
A large part of the juggling in the API is to make the API safer for
its maintenance and consumers alike.
For the maintenance of the API we e.g. avoid malloc()-ing the
"pp->pfd", ensuring that SANITIZE=address and other similar tools will
catch any unexpected misuse.
For API consumers we take pains to never pass the non-NULL "out"
buffer to an API user that provided the "ungroup" option. The
resulting code in t/helper/test-run-command.c isn't typical of such a
user, i.e. they'd typically use one mode or the other, and would know
whether they'd provided "ungroup" or not.
We could also avoid the strbuf_init() for "buffered_output" by having
"struct parallel_processes" use a static PARALLEL_PROCESSES_INIT
initializer, but let's leave that cleanup for later.
Using a global "run_processes_parallel_ungroup" variable to enable
this option is rather nasty, but is being done here to produce as
minimal of a change as possible for a subsequent regression fix. This
change is extracted from a larger initial version[1] which ends up
with a better end-state for the API, but in doing so needed to modify
all existing callers of the API. Let's defer that for now, and
narrowly focus on what we need for fixing the regression in the
subsequent commit.
It's safe to do this with a global variable because:
A) hook.c is the only user of it that sets it to non-zero, and before
we'll get any other API users we'll refactor away this method of
passing in the option, i.e. re-roll [1].
B) Even if hook.c wasn't the only user we don't have callers of this
API that concurrently invoke this parallel process starting API
itself in parallel.
As noted above "A" && "B" are rather nasty, and we don't want to live
with those caveats long-term, but for now they should be an acceptable
compromise.

The short upstream state indicator inherits the colour of the last short
state indicator before it (if there is one), and the sparsity state
indicator inherits this colour as well. This behaviour was introduced by
0ec7c23cdc (git-prompt: make upstream state indicator location
consistent, 2022-02-27), while before this change the aforementioned
indicators were white/the default text colour. Some examples to
illustrate this behaviour (assuming all indicators are enabled and
colourization is on):
* If there is something in the stash, both the '$' and the short
upstream state indicator following it will be blue.
* If the local tree has new, untracked files and there is nothing in
the stash, both the '%' and the short upstream state indicator
will be red.
* If all local changes are added to the index and the stash is empty,
both the '+' and the short upstream state indicator following it will
be green.
* If the local tree is clean and there is nothing in the stash, the
short upstream state indicator will be white/${default text colour}.
This appears to be an unintended side-effect of the change, and makes
little sense semantically (e.g. why is it bad to be in sync with
upstream when you have uncommitted local changes?). The cause of the
change in colourization is that previously, the short upstream state
indicator appeared immediately after the rebase/revert/bisect/merge
state indicator (note the position of $p in $gitstring):
local f="$h$w$i$s$u"
local gitstring="$c$b${f:+$z$f}${sparse}$r$p"
Said indicator is prepended with the clear colour code, and the short
upstream state indicator is thus also uncoloured. Now, the short
upstream state indicator follows the sequence of colourized indicators,
without any clearing of colour (again note the position of $p, now in
$f):
local f="$h$w$i$s$u$p"
local gitstring="$c$b${f:+$z$f}${sparse}$r${upstream}"
If the user is in a sparse checkout, the sparsity state indicator
follows a similar pattern to the short upstream state indicator.
However, clearing colour of the colourized indicators changes how the
sparsity state indicator is colourized, as it currently inherits (and
before the change referenced also inherited) the colour of the last
short state indicator before it. Reading the commit message of the
change that introduced the sparsity state indicator, afda36dbf3
(git-prompt: include sparsity state as well, 2020-06-21), it appears
this colourization also was unintended, so clearing the colour for said
indicator further increases consistency.
Make the colourization of these state indicators consistent by making
all colourized indicators clear their own colour. Make colouring of $c
dependent on it not being empty, as it is no longer being used to colour
the branch name. Move clearing of $b's prefix to before colourization so
it gets cleared properly when colour codes are inserted into it. These
changes make changing the layout of the prompt less prone to unintended
colour changes in the future.
Change coloured Bash prompt tests to reflect the colourization changes:
* Move the colour codes to wrap the expected content of the expanded
$__git_ps1_branch_name in all tests.
* Insert a clear-colour code after the symbol for the first indicator
in "prompt - bash color pc mode - dirty status indicator - dirty
index and worktree", to reflect that all indicators should clear
their own colour.

After generating diffs for each range to be compared using a 'git log'
invocation, range-diff.c::read_patches looks for the "diff --git" header
in those diffs to recognize the beginning of a new change.
In a project with submodules, and with 'diff.submodule=log' set in the
config, this header is missing for the diff of a changed submodule, so
any submodule changes are quietly ignored in the range-diff.
When 'diff.submodule=diff' is set in the config, the "diff --git" header
is also missing for the submodule itself, but is shown for submodule
content changes, which can easily confuse 'git range-diff' and lead to
errors such as:
error: git apply: bad git-diff - inconsistent old filename on line 1
error: could not parse git header 'diff --git path/to/submodule/and/some/file/within
'
error: could not parse log for '@{u}..@{1}'
Force the submodule diff format to its default ("short") when invoking
'git log' to generate the patches for each range, such that submodule
changes are always detected.
Add a test, including an invocation with '--creation-factor=100' to
force the second commit in the range not to be considered a complete
rewrite, in order to verify we do indeed get the "short" format.

When a commit is parsed, it pretends to have a different (possibly
empty) list of parents if there is graft information for that commit.
But there is a bug that could occur when a commit is parsed, the graft
information is updated (for example, when a shallow file is rewritten),
and the same commit is subsequently used: the parents of the commit do
not conform to the updated graft information, but the information at the
time of parsing.
This is usually not an issue, as a commit is usually introduced into the
repository at the same time as its graft information. That means that
when we try to parse that commit, we already have its graft information.
But it is an issue when fetching a shallow point directly into a
repository with submodules. The function
assign_shallow_commits_to_refs() parses all sought objects (including
the shallow point, which we are directly fetching). In update_shallow()
in fetch-pack.c, assign_shallow_commits_to_refs() is called before
commit_shallow_file(), which means that the shallow point would have
been parsed before graft information is updated. Once a commit is
parsed, it is no longer sensitive to any graft information updates. This
parsed commit is subsequently used when we do a revision walk to search
for submodules to fetch, meaning that the commit is considered to have
parents even though it is a shallow point (and therefore should be
treated as having no parents).
Therefore, whenever graft information is updated, mark the commits that
were previously grafts and the commits that are newly grafts as
unparsed.

The `--preserve-merges` option was removed by v2.34.0. However
users may not be aware that it is also a Pull configuration option,
which is still offered by major IDE vendors such as Visual Studio.
Extend the `--preserve-merges` die message to also direct users to
the possible use of the `preserve` option in the `pull.rebase` config.
This is an additional 'belt and braces' information statement.
