Fair enough, I described this incorrectly. As it stands, they're
remaining as "edited", not changing to "up-to-date".

I think it was only for multi-file commits, and when the file isn't
loaded in a buffer.
If it's in a buffer, I think that buffer's modeline updates to "-",
but closing the file and revisiting it shows the ":" again.
Running a "cvs update" outside of emacs also has no effect so it looks
like it's state kept internally by VC (if it was (re)checking
CVS/Entries it would/should see it as unmodified again).

I'll re-bootstrap emacs to ensure the compiled lisp files are properly
in sync, and I'll try to set up a scenario with emacs -Q.
