You don't need to pretend.  I'm quite sure Chong wrote the code and
Richard just committed the change, for some reason.  CVS doesn't have
the equivalent of the --author switch to the 'commit' command, so you
will see a lot of similar cases in old commits.  E.g., all of my
commits were done by Richard or others at first, until I got write
access several years later.

There's nothing funky here.
