Subject: [BUG] "git stash -- path" reports wrong unstaged changes
Date: Fri, 17 Mar 2017 10:50:39 -0400
Message-ID: <20170317145039.dmcb3qyqbzfvtmgz@sigill.intra.peff.net> (raw)

I used "git stash -- path" for the first time today and happened to
notice an oddity. If I run:

	git init -q repo
	cd repo
	
	for i in one two; do
		echo content >$i
		git add $i
	done
	git commit -qm base
	
	for i in one two; do
		echo change >$i
	done
	git stash -- one

it says:

  Saved working directory and index state WIP on master: 20cfadf base
  Unstaged changes after reset:
  M	one
  M	two

Even though "one" no longer has unstaged changes.

If I run with GIT_TRACE=1, that message is generated by:

  git reset -- one

which makes sense. At that stage we've just reset the index, but the
working tree file still has modifications. In the non-pathspec case we
run "git reset --hard", which takes care of the index and the working
tree.

It's really "checkout-index" that cleans the working tree, but it
doesn't have porcelain finery like an "Unstaged changes" message. I
think the patch below would fix it, but I wonder if we can do it in a
way that doesn't involve calling diff-files twice.
