I don't mean this. The problem is how vc caches values. It uses file
properties, and in case `vc-file-getprop' returns nil, it assumes the
property is not cached. Consequently, we can never cache the value nil
for the file property `vc-state'. That is a regression, compared with
caching the value `unregistered'.
Best regards, Michael.
