It is my experience that the SysV "what" program can see both "@(#)"
SCCS comments and $foo$ RCS comments.  There is a "BUGS" section in
what(1) man page that says this:

BUGS
     As BSD UNIX is not licensed to distribute SCCS this is a rewrite of the
     what command which is part of SCCS, and may not behave exactly the same
     as that command does.

I think that it would be nice if "what" could show both types.  Any takers?
