--help, --version: New options, for conformance to GNU coding standards.

(Copyright, Help, Id): New variables, for above.
(rlog): Use -q option with cvs log, to avoid useless chatter.

Treat logs of "Initial revision" (RCS) or "file F was initially added
on branch B." (CVS) as if they said "New file.", for consistency with
change log entries.
