Subject: [PATCH 2/2] vc-git.el: make sure bug#21559 applies to git status
The fix for Bug#21559 is mostly right, but the one command we were
trying to protect, git status --porcelain, doesn't go through
vc-git-command and doesn't actually get the GIT_OPTIONAL_LOCKS=0 treatment.
* lisp/vc/vc-git.el (vc-git--call): Override GIT_OPTIONAL_LOCKS=0
during revert-buffer-in-progress-p
