Git dropped the period from its "ambiguous SHA1" error message in commit
0c99171ad2 ("get_short_sha1: mark ambiguity error for translation"),
circa 2016.  Drop the period from checkpatch's associated query so as to
match both the old and new error messages.

Thanks.

Did git ever change to actually support human readable
messages in multiple languages?

If so, this won't work for non-english output.

It probably doesn't matter though.

Yep, e.g.:

  error: Kurzer SHA-1 745f ist mehrdeutig.

> If so, this won't work for non-english output.

Yep again.  The next check for 'fatal: ambiguous argument' obviously fails
as well and checkpatch ends up using git's error message as the id and
description.

  ERROR: Please use git ... - ie: 'commit error: Kurze ("")'

Does git exit with unique failure codes?
If so, maybe the waitid/siginfo_t error could be used instead.

* [PATCH] checkpatch: Make git output use LANGUAGE=en_US.utf8

git output parsing depends on the language being en_US english.

Make the backtick execution of all `git <foo>` commands set the
LANGUAGE of the process to en_US.utf8 before executing the actual
command using `export LANGUAGE=en_US.utf8; git <foo>`.

Because the command is executed in a child process, the parent
LANGUAGE is unchanged.

Nope, AFAICT usage errors get exit(129) and everything else gets exit(128).
