[PATCH v2 2/3] stash: pass the pathspec argument to git reset

[Thomas Gummerer <t.gummerer@gmail.com>]

For "git stash -p --no-keep-index", the pathspec argument is currently
not passed to "git reset".  This means that changes 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>".
