Unfortunately, cvs diff does not seem to work with the -N option
when it is a new file with nothing to compare against,
so I tried to fake the cvs/rcs header based on a manual diff
generated before I renamed the file.

Please let me know if the following bare diff works
with your patch on your system,
then I know I can just omit the extra cvs/rcs junk.

Thanks. Take care, Brian Inglis
