If we just want to document the years that have any changes at all
(i.e. not differentiate between small and big changes), it is a fairly
easy task to accomplish (and automate) --

For each file do:

1) cvs update FILE
2) cvs log FILE
3) find the YEAR of each log entry and put it into a list
   (if not already there)
4) sort the list
5) update the copyright in FILE using that list
6) cvs commit -m"Updated copyright years" FILE

In the process, all 2-digit years would be converted into 4-digit
years.

Of course, step 5 and 6 should be avoided if the current list of
years in FILE is already correct.

A Miles pointed out, this will lead to some merge conflicts, but since
this is legal stuff, we have to accept that inconvenience.

I can do this if you approve.
