[PATCH v6 6/9] detached-stash: simplify git stash branch

From: Jon Seymour <jon.seymour@gmail.com>

Message-ID: <1282363744-4924-7-git-send-email-jon.seymour@gmail.com>
In-Reply-To: <1282363744-4924-1-git-send-email-jon.seymour@gmail.com>

This patch teaches git stash branch to tolerate stash-like arguments.

In particular, a stash is only required if an argument isn't specified and the stash is only dropped if a stash entry reference was specified or implied.

The implementation has been simplified by taking advantage of assert_stash_like() and the variables established by parse_flags_and_rev().
