Try doing a "cvs status" on some of the different files, to see if
they'e on the branch or the HEAD (or just inspect the NetBSD version
number part of the diff. Branch versions have four fields if they're
changed from the HEAD, HEAD versions always two). I suspect that -D
overrides the branch tag, and that time-travel on a branch doesn't
really work, even though some folks have reported that "it works for
them".
