Maybe I wasn't clear enough.  I got no errors, but flymake incorrectly
fontified the buffer.  Anyway, I tried to look into why this happened
even after applying your patch and it turned out that
vc-find-revision-no-save also calls set-auto-mode.  So, I don't know if
the following patch is correct, but together with your patch it does
solve the original issue.

diff --git a/lisp/vc/vc.el b/lisp/vc/vc.el
