Merge branch 'tg/stash-untracked-with-pathspec-fix' into next

"git stash push -u -- <pathspec>" gave an unnecessary and confusing
error message when there was no tracked files that match the
<pathspec>, which has been fixed.

* tg/stash-untracked-with-pathspec-fix:
stash: drop superfluos pathspec parameter
