C style: use standard style for "TRANSLATORS" comments
Change all the "TRANSLATORS: [...]" comments in the C code to use the
regular Git coding style, and amend the style guide so that the
example there uses that style.
This custom style was necessary back in 2010 when the gettext support
was initially added, and was subsequently documented in commit
cbcfd4e3ea ("i18n: mention "TRANSLATORS:" marker in
Documentation/CodingGuidelines", 2014-04-18).
GNU xgettext hasn't had the parsing limitation that necessitated this
exception for almost 3 years. Since its 0.19 release on 2014-06-02
it's been able to recognize TRANSLATOR comments in the standard Git
comment syntax[1].
Usually we'd like to keep compatibility with software that's that
young, but in this case literally the only person who needs to be
using a gettext newer than 3 years old is Jiang Xin (the only person
who runs & commits "make pot" results), so I think in this case we can
make an exception.
This xgettext parsing feature was added after a thread on the Git
mailing list[2] which continued on the bug-gettext[3] list, but we
never subsequently changed our style & styleguide, do so.
There are already longstanding changes in git that use the standard
comment style & have their TRANSLATORS comments extracted properly
without getting the literal "*"'s mixed up in the text, as would
happen before xgettext 0.19.
Commit
7ff2683253 ("builtin-am: implement -i/--interactive",
2015-08-04) added one such comment, which in commit
df0617bfa7 ("l10n:
git.pot: v2.6.0 round 1 (123 new, 41 removed)", 2015-09-05) got picked
up in the po/git.pot file with the right format, showing that Jiang
already runs a modern xgettext.
The xgettext parser does not handle the sort of non-standard comment
style that I'm amending here in sequencer.c, but that isn't standard
Git comment syntax anyway. With this change to sequencer.c & "make
pot" the comment in the pot file is now correct:
#. TRANSLATORS: %s will be "revert", "cherry-pick" or
-#. * "rebase -i".
+#. "rebase -i".

am: handle "-h" argument earlier
If the user provides "-h" on the command line, then our
parse_options() invocation will show a usage message and
quit. But if "-h" is the only argument, the git wrapper
behaves specially: it ignores our RUN_SETUP flag and calls
cmd_am() without having done repository setup at all. This
is due to
99caeed05 (Let 'git <command> -h' show usage
without a git dir, 2009-11-09).
Before cmd_am() calls parse_options(), though, it runs a few
other setup functions. One of these is am_state_init(),
which uses git_pathdup() to set up the default rebase-apply
path. But calling git_pathdup() when we haven't done
repository setup will fall back to using ".git". That's
mostly harmless (since we won't use the value anyway), but
is forbidden since
b1ef400eec ("setup_git_env: avoid blind
fall-back to ".git"", 2016-10-20), and we now BUG().
We can't easily move that setup to after the parse_options()
call; the point is to set up defaults that are overwritten
by the option parsing. Instead, we'll detect the "-h" case
early and show the usage then. This matches the behavior of
other builtins which have a similar setup-ordering issue
(e.g., git-branch).

pack-objects & index-pack: add test for --threads warning
Add a test for the warning that's emitted when --threads or
pack.threads is provided under NO_PTHREADS=YesPlease. This uses the
new PTHREADS prerequisite.
The assertion for C_LOCALE_OUTPUT in the latter test is currently
redundant, since unlike index-pack the pack-objects warnings aren't
i18n'd. However they might be changed to be i18n'd in the future, and
there's no harm in future-proofing the test.
There's an existing bug in the implementation of pack-objects which
this test currently tests for as-is. Details about the bug & the fix
are included in a follow-up change.

test-lib: add a PTHREADS prerequisite
Add a PTHREADS prerequisite which is false when git is compiled with
NO_PTHREADS=YesPlease.
There's lots of custom code that runs when threading isn't available,
but before this prerequisite there was no way to test it.

grep: move is_fixed() earlier to avoid forward declaration
Move the is_fixed() function which are currently only used in
compile_regexp() earlier so it can be used in the PCRE family of
functions in a later change.
