since 5e1f28d (bisect--helper: reimplement `bisect_visualize()` shell
function in C, 2021-09-13) `git bisect visualize` uses exists_in_PATH()
to check wether it should call `gitk`, but exists_in_PATH() relies on
locate_in_PATH() which currently only understands POSIX-ish PATH variables
(a list of paths, separated by colons) on native Windows executables
we encounter Windows PATH variables (a list of paths that often contain
drive letters (and thus colons), separated by semicolons). Luckily we do
already have a function that can lookup executables on windows PATHs:
path_lookup(). Implement a small replacement for the existing
locate_in_PATH() based on path_lookup().

During a series of "fixup" and/or "squash" commands, the interactive
rebase accumulates a commit message from all the commits that are being
squashed together. If one of the commits has conflicts when it is picked
and the user chooses to skip that commit then we need to remove that
commit's message from accumulated messages. To do this 15ef69314d
(rebase --skip: clean up commit message after a failed fixup/squash,
2018-04-27) updated commit_staged_changes() to reset the accumulated
message to the commit message of HEAD (which does not contain the
message from the skipped commit) when the last command was "fixup" or
"squash" and there are no staged changes. Unfortunately the code to do
this contains two bugs.
(1) If parse_head() fails we pass an invalid pointer to
unuse_commit_buffer().
(2) The reconstructed message uses the entire commit buffer from HEAD
including the headers, rather than just the commit message.
The first issue is fixed by splitting up the "if" condition into several
statements each with its own error handling. The second issue is fixed
by finding the start of the commit message within the commit buffer
using find_commit_subject().
The existing test added by 15ef69314d is modified to show the effect of
this bug. The bug is triggered when skipping the first command in the
chain (as the test does before this commit) but the effect is hidden
because opts->current_fixup_count is set to zero which leads
update_squash_messages() to recreate the squash message file from
scratch overwriting the bad message created by
commit_staged_changes(). The test is also updated to explicitly check
the commit messages rather than relying on grep to ensure they do not
contain any stray commit headers.
To check the commit message the function test_commit_message() is moved
from t3437-rebase-fixup-options.sh to test-lib.sh. As the function is
now publicly available it is updated to provide better error detection
and avoid overwriting the commonly used files "actual" and "expect".
Support for reading the expected commit message from stdin is also
added.

When we process a user's name (as in user.name), we strip all
leading and trailing crud from it. Right now, we consider a dot
a crud character, and strip it off.
However, this is unsuitable for many personal names because humans
frequently have abbreviated suffixes, such as "Jr." or "Sr." at the end
of their names, and this corrupts them. Some other users may wish to
use an abbreviated name or initial, which will pose a problem especially
in cultures that write the family name first, followed by the personal
name.
Since the current approach causes lots of practical problems, let's
avoid it by no longer considering a dot to be crud.
Note that "." in the name forces the entire name to be quoted to
please mailers, but stripping "." only at the beginning and the end
does not help a name with "." in the middle (like "brian m. carlson")
so this change will not make it much worse. A name like "Given
Family, Jr." that did not have to be quoted now would need to be, in
order to be placed on the e-mail headers, though.
This is based on a weather-balloon patch by Jeff King sent in Aug 2021

"git bundle" passes the progress control options to "git pack-objects"
by parsing and then recreating them explicitly. Simplify that process
by using OPT_PASSTHRU_ARGV instead.
This also fixes --no-quiet, which has been doing the same as --quiet
since its introduction by 79862b6b77 (bundle-create: progress output
control, 2019-11-10) because it had been defined using OPT_SET_INT with
a value of 0, which sets 0 when negated as well.

Finding mistakes in and improving your own patches is a good idea,
but doing so too quickly is being inconsiderate to reviewers who
have just seen the initial iteration and taking their time to review
it. Encourage new developers to perform such a self review before
they send out their patches, not after. After sending a patch that
they immediately found mistakes in, they are welcome to comment on
them, mentioning what and how they plan to improve them in an
updated version, before sending out their updates.

While we could technically fix each and every bug on top of the
commit that introduced it, it is not necessarily practical. For
trivial and low-value bugfixes, it often is simpler and sufficient
to just fix it in the current maintenance track, leaving the bug
unfixed in the older maintenance tracks.
Demote the "use older maintenance track to fix old bugs" as a side
note, and explain that the choice is used only in exceptional cases.

The 'next' branch is primarily meant to be a testing ground to make
sure that topics that are reasonably well done work well together.
Building a new work on it would mean everything that was already in
'next' must have graduated to 'master' before the new work can also
be merged to 'master', and that is why we do not encourage basing
new work on 'next'.

Replace all cases of `\s` with ` ` as it is not part of POSIX BRE or ERE
and therefore not all versions of grep handle it.
For the same reason all cases of `\S` are replaced with `[^ ]`. It is
not an exact replacement but it is close enough for this use case.
Also, do not write `\+` in BRE and expect it to mean 1 or more;
it is a GNU extension that may not work everywhere.
