Merge branch 'js/apply-recount-allow-noop'

When editing a patch in a "git add -i" session, a hunk could be
made to no-op.  The "git apply" program used to reject a patch with
such a no-op hunk to catch user mistakes, but it is now updated to
explicitly allow a no-op hunk in an edited patch.

* js/apply-recount-allow-noop:
  apply --recount: allow "no-op hunks"
