cvs annotate cmacexp.el > files.ann

    grep "..-...-05" cmacexp.ann | wc
         13     104     962

    13 < 15 => don't add copyright year.

That would be easy but it wouldn't give the right answer.  counting
lines changed is not the same As counting the size of the changes.  If
the change is to rename foo to bar everywhere, that really counts as
just one word of change even though it may be repeated many times.

    How about developing a script to update these changes automatically?

This is not a mechanical question and it can't be answered by a script.
