Subject: [PATCH 1/2] Fix for: "25.0.50; auto-revert-mode breaks git rebase"
(Bug#21559)
* lisp/autorevert.el (auto-revert-handler):
Set "revert-buffer-in-progress-p" flag before calling
"vc-refresh-state".
* lisp/vc/vc-git.el (vc-git-command):
If "revert-buffer-in-progress-p" flag is set, prepend
"GIT_OPTIONAL_LOCKS=0" to "process-environment". (Bug#21559)
