Of course!

Until now I even didn't realize this was broken by my patch. Sorry, but
I have been in hospital last year, and when I recovered there were too
many messages to scan.

I'll check what could be done. I'll return later.

Best regards, Michael.

PS: the discussion about my other changes in vc-tests.el shall be moved
to the emacs-devel ML. Let's restart it there, when this problem is solved.
