[PATCH] bash completion: factor submodules into dirty state

[Thomas Rast <trast@student.ethz.ch>]

In the implementation of GIT_PS1_SHOWDIRTYSTATE in 738a94a (bash:
offer to show (un)staged changes, 2009-02-03), I cut&pasted the
git-diff invocations from dirty-worktree checks elsewhere, carrying
along the --ignore-submodules option.

As pointed out by Kevin Ballard, this doesn't really make sense: to
the _user_, a changed submodule counts towards uncommitted changes.

No good reason; I really do remember cut&pasting the checks, though
I'm not sure from where.

I don't really use submodules, so I'll just trust your judgements that
it's better to factor them into the status.
