Running the command yields:
$ cvs rename fred.c fred.cpp
cvs rename: Warning: rename is still experimental and may not behave as you
would expect

RTFM yields:
"Rename is currently experimental."

March Hare Software are currently planning to deliver the following features
in CVSNT 2.6.01: 
Rename / Move / Directory Rename 

What could be more explicit than that?

Oh, from your OP, "Also, there is an annoyance: the documentation
indicates  after a move, cvs commit should be run from the parent
directory. I find cvs commit must be run from within each directory where a
rename action has occurred to actually do anything. When run from a parent
directory, cvs commit does nothing."

Again, RTFM: "Rename information is held at the directory level, so the
rename/move is not committed to the repository until cvs commit is called
on the directory containing the file." so don't be surprised that when
doing a move you need to commit in both the *source* and *destination*

No really, since rename is *experimental*.

Yes, but then again Snoopy would fly over Charlie, tell him not to play with
experimental commands, then fly off to fight the Red Barron.
