Revision 82561

``Oh, by the way: the same procedure as last year?
  The same procedure as _every_ year, James!''

So, a lot of touched files here, but it's just a tiny harmless patch.
As every year we bump up the year number in our copyright headers.

1. "199x-1998" => "199x-1999"
2. "1998"      => "1998-1999"
