I think you're seeing the effect of this:
(defun vc-find-root (file witness)
"Find the root of a checked out project.
The function walks up the directory tree from FILE looking for WITNESS.
If WITNESS if not found, return nil, otherwise return the root."
(let ((locate-dominating-stop-dir-regexp
(or vc-ignore-dir-regexp locate-dominating-stop-dir-regexp)))
(locate-dominating-file file witness)))
vc-ignore-dir-regexp defaults to locate-dominating-stop-dir-regexp,
though, so could it be that you're setting
locate-dominating-stop-dir-regexp after you've loaded vc.el?
