The one that I see most often ( and use here ) is CVSGUI (
http://www.wincvs.org/ ), which includes a CVS command-line client despite
the name. ( The command-line CVS might be from CVSNT,
http://www.cvsnt.com/cvspro/ ).

So I thought I'd try a few scenarios, since I have it installed:

------

The message "is not recognized as an internal or external command..." is
from the operating system, so CVS is at least trying to launch an editor in
those cases.

So to answer your question, at least in part, there is no current good
behavior to emulate. At least on this version of CVS:

Concurrent Versions System (CVSNT) 2.0.51d (client/server)

Copyright (c) 1989-2001 Brian Berliner, david d `zoo' zuhn,
Jeff Polk, and other authors
CVSNT version (Aug 19 2004) Copyright (c) 1999-2004 Tony Hoyle and others
see http://www.cvsnt.org

If you have any other combinations that might make sense, let me know, and
I'll give it a try.
