[PATCH 5/5] git-completion.bash: consolidate no-subcommand case for _git_stash()

[Denton Liu <liu.denton@gmail.com>]

We have a separate if case for when no subcommand is given. It is
simpler to just consolidate this logic into the case statement below.

It would be nice to complete remove the magic that deals with indices
and replace it with what was originally there,

	if [ -z "$subcommand" -a -n "$(__git_find_on_cmdline "-p")" ]; then
	        subcommand="push"
	fi

but this gives a slightly incorrect completion. In the case where we're
attempting to complete `git stash -a <TAB>` we will get the subcommands
back as a respose instead of the completions for `git stash push`, which
is what we'd expect. We could potentially hardcode all of the short
options but that would be too much work to maintain so we stick with the
index solution.
