Trying to reduce it to a formula for files whose history that we're
not familiar with:

e.g choosing cmacexp.el at random

cvs annotate cmacexp.el > files.ann

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

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

What are the consequences of adding a year where no copyrightable changes
were made? Presumably this is less serious than not adding a year where
such changes were made.

How about developing a script to update these changes automatically?
