Subject: [PATCH v11 14/22] stash: convert show to builtin
Date: Fri, 23 Nov 2018 01:05:34 +0200 [thread overview]
Message-ID: <3e141cf7471ea0db65a5308105d549cd59388a6a.1542925164.git.ungureanupaulsebastian@gmail.com> (raw)
In-Reply-To: <cover.1542925164.git.ungureanupaulsebastian@gmail.com>
Add stash show to the helper and delete the show_stash, have_stash,
assert_stash_like, is_stash_like and parse_flags_and_rev functions
from the shell script now that they are no longer needed.
In shell version, although `git stash show` accepts `--index` and
`--quiet` options, it ignores them. In C, both options are passed
further to `git diff`.
