vc.el complaint about reference to free variable `file'

[martin rudalics]

When compiling vc.el I get the complaint

In vc-next-action:
vc.el:1510:70:Warning: reference to free variable `file'

IIUC the offending occurrence is the "file" below:

     ((stringp state)
      (let ((revision
             (if verbose
                 (read-string "Revision to steal: ")
               (vc-working-revision file))))
                                    ^^^^
        (dolist (file files) (vc-steal-lock file revision state))))


Also a ChangeLog entry is missing for this change in revision 1.492:

-  (let ((bname (if fname (get-file-buffer fname) buffer-file-name)))
+  (let ((bname (if fname (get-file-buffer fname) (current-buffer))))
