Yeah, I noticed this while playing around with patch 2. This seems
like an improvement to me. Unlike the other patches (which are just
tweaking quietness), I think this one really needs a test.

Also, s/changed/changes/ above.

I think it's OK. You can't select (or not select) changes from the index
anyway. TBH, I kind of wonder if "git stash -p --no-keep-index" makes
any sense at all.

I did notice one other case while looking at this that I think is much
more serious. The "read-tree" call in the non-patch-mode case doesn't
use a pathspec either. So if we have our same setup where "one" and
"two" have unstaged changes and we do:

  git stash push -k one

Then we stash "one", but the change in "two" is wiped out completely!

I don't think read-tree takes pathspecs, so it would have to drop the
"-u" and replace it with checkout-index. I'm confused about why we would
need it in the first place, though. We should have already dealt with
the working tree files in the earlier block, so there should be nothing
to checkout.

The "-u" goes all the way back to 7bedebcaa (stash: introduce 'stash
save --keep-index' option, 2008-06-27). I wonder if it has always been
unnecessary, but we never noticed because it's just a noop.
