According to the Berne Convention, a copyright notice is not even required
in order to have copyright protection, so whatever we right there would be
legal.
According to the gnu license how to
<http://www.gnu.org/copyleft/gpl-howto.html>
(which is the license we are using), the proper way is "If several people
helped write the code, use all their names".

No, it means that there has been a release at least every year from
1999-2010, and that Jan and Anthony both hold copyright, so both of their
permissions are required in order to have any use not permitted in the
explicit license terms.

No -- it would be a disaster trying to keep track in the header of which
dates each user made modifications to the code.
But, I'm not a lawyer, so don't take my legal advice.
