pcl-cvs describe-mode

It sure would be nice if `C-h m' in cvs-mode showed the keymap, especially with some of the rather non-obvious key bindings in that mode (M-DEL for `remove all marks', `O' for `update', etc). Most other `civilized' modes show the key bindings when you do `C-h m'. What's different about PCL-CVS? Is it because we're using that ikky `easy-mmode'? Or maybe it's because pcl-cvs is a derived mode, derived from fundamental-mode. In any case it's not very user-friendly behavior.
