(I also wrote a "diff" type program...)

What we need to know is how "compatible" the various public domain diffs
are.  Can GNU diff be used with RCS, for instance?  I find the public
domain diff works well enough (diff -cb) for Larry Wall's patch program,
but I've heard complaints that there are command options used by RCS that
don't exist in the public domain version.

Can anyone summarize the compatibility questions or point to a diff that
RCS can use (public of course).
