Renaming read-only files

Yo.

I was about to start using rcs again, when I realized that an old patch
(~mint-1.09.something) has not made it into the newer releases.
The trouble are with renaming read-only files. As it is now, this is
illegal, and rcs fails. So, I introduce this little patch, which enables
the super-user or the owner of a file to rename it - even if it is
write-protected.
