vc-rename-file doesn't work for CVS

[Zhang Wei]

While I'm trying to rename a file with 'vc-rename-file', the old file
was deleted from my working copy, and a new file was created,
everything seems ok, but if I checkout a fresh new working copy, the
old file and the new one was check out all together.  It seems like
that the "cvs remove" commond doen't issue at all.
