Hotfix.

* tg/stash-doc-typofix:
  git-stash.txt: remove extra square bracket

Hotfix.

* pc/submodule-helper:
  submodule deinit: handle non existing pathspecs gracefully

Hotfix for recently graduated topic that give help to completion
scripts from the Git subcommands that are being completed

* nd/parseopt-completion:
  t9902: disable test on the list of merge-strategies under GETTEXT_POISON
  completion: clear cached --options when sourcing the completion script

This fixes a regression introduced in 2e612731 (submodule: port
submodule subcommand 'deinit' from shell to C, 2018-01-15), when
handling pathspecs that do not exist gracefully. This restores the
historic behavior of reporting the pathspec as unknown and returning
instead of reporting a bug.

In 1ada5020 ("stash: use stash_push for no verb form", 2017-02-28),
when the pathspec argument was introduced in 'git stash', that was also
documented.  However I forgot to remove an extra square bracket after
the '--message' argument, even though the square bracket should have
been after the pathspec argument (where it was also added).

Remove the extra square bracket after the '--message' argument, to show
that the pathspec argument should be used with the 'push' verb.

While the pathspec argument can be used without the push verb, that's a
special case described later in the man page, and removing the first extra
square bracket instead of the second one makes the synopis easier to
understand.

The code to learn the list of merge strategies from the output of
"git merge -s help" forces C locale, so that it can notice the
message shown to indicate where the list starts in the output.

However, GETTEXT_POISON build corrupts its output even when run in
the C locale, and we cannot expect this test to succeed.
