[PATCH v1] stash show: fix breakage in 1.7.3

[Jon Seymour <jon.seymour@gmail.com>]

The detached-stash series regressed support for
   git stash show stash@{0}

due to a faulty assumption that:
   git rev-parse --no-revs -- stash@{0}

would treat stash@{0} as a revision reference and
thus not output it.

This patch restores the behaviour of git stash show
so that git rev-parse is not used for parsing flags
and only flag like options are assigned to
the FLAGS variable.

It has been tested with Brandon Casey's improved t3903 tests.

This revision further simplifies the parsing code
by removing use of git rev-parse for FLAGS parsing
altogether.
