Diffing previous revision

[Vince Rice]

I am constantly needing to diff a source file against
the previous revision.  That currently means I have to
do a log/rlog to determine the previous revision, then
do the cvs diff.

Is there a way to do this automagically, i.e. be able
to say "previous revision" in the -r, without having
to do the log/rlog?  And if there's not, would someone
consider it as an enhancement request?

Perhaps
  cvs diff -r PREV source.c
or something.

Thanks,

Vince
