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`.
