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.
