Re: Adding missing copyright years

[Richard Stallman]

    What I mean is, if someone made a significant change to foo.el in
    2003, and some other people did another significant change to foo.el
    in 2005, so there's no remaining code in foo.el from the 2003 change,
    should the copyright be "2003, 2005" or just "2005"? I think is the
    later

If the 2003 code was simply replaced, then 2003 should not appear
in the list.
