A reminder: the payoff for getting it right would be another significant speedup in (vc-dired-hook), which would translate to a faster C-x v d display. Remarkably, it looks as if the code does not actually depend in any significant way on the nil return from (vc-state file) meaning that FILE is unregistered. Tests that might have used this method use vc-backend instead. So introducing an 'unregistered state shouldn't actually break anything. Alex Harsanyi: A cvs-ignorable-file-p would actually be useful, if you're still interested. Under later systems it's faster to get this by doing a bit of estra parsing of rge status report. -- Eric S.
