(defun vc-git-workfile-unchanged-p (file)
;; The reason this does not use the result of vc-git-state is that
;; git-diff-index (used by vc-git-state) doesn't refresh the cached
;; stat info, so if the file has been modified it will always show
;; up as modified in vc-git-state, even if the change has been
;; undone, until git-update-index --refresh is run.
;; OTOH the vc-git-workfile-unchanged-p implementation checks the
;; actual content, so it will detect the case of a file reverted
;; back to its original state.
;; The ideal implementation would be to refresh the stat cache and
;; then call vc-git-state, but at the moment there's no git command
;; to refresh a single file, so this will have to be added first.
