a tiny patch for _cvs

["Akinori MUSHA" <knu@xxxxxxxxxxxx>]

Hello again,

We found that the compdef for cvs(1) didn't grok the -R option, which
had been introduced by FreeBSD (and later adopted by OpenBSD) quite
some time ago.

As the option is very useful for resolving the permission issue and
improving the performance over NFS or SSH, we really get used to it.
We'd appreciate if you could kindly merge the attached patch.


Regards,
