[PATCH/RFC 3/3] stash: pass the pathspec argument to git reset

For "git stash -p --no-keep-index", the pathspec argument is currently
not passed to "git reset".  This means that changed that are staged but
that are excluded from the pathspec still get unstaged by git stash -p.

Make sure that doesn't happen by passing the pathspec argument to the
git reset in question, bringing the behaviour in line with "git stash --
<pathspec>".

So this make things a bit inconsistent in for example the following
situation:

    $ git status -s
     M git-stash.sh
    M  read-cache.c

where using git stash -p --no-keep-index, when only changes in
git-stash.sh are added to the stash would reset read-cache.c, but with
git stash -p --no-keep-index -- git-stash.sh, read-cache.c would not
be reset.  

However it does bring things more in line with git stash --
<pathspec>, so I think this is an improvement.
