Add missing copyright header caught by Ben's test scripts.  The cvs log shows that Frerich Raabe is the only person to work on the file, so I've made sure that the statement indicates it is his code.

I'm guessing the license is GPL-v2 at this point, and if I'm wrong it won't matter, but I'd appreciate it if you would update the license as appropriate Frerich. ;-)
