There are about 2000 files with copyright notices.  If these are all done
manually, changing them twice seems to me to be an inefficient way of working.
If, as Stefan suggests, only those changed in 2006 need their copyright changed
again then maybe it's not so bad.

Yes, I see its less straightforward than I had hoped.

I'll start thinking about how to do it.  Since the copyright notices won't be
all the same any script must be able to handle the differences.  I'm thinking
of something that keeps the user in the loop, like query replace or ediff,
where he will be presented with a proposed change which he can decline
or accept.
