This only requires that the applied license must be mentioned. It
doesn't require mentioning that the program was modified.
It would mean that when you add changes under the GPL, you are required
to mention in the intro screen that the GPL applies to the program. I'm
not really happy with that. I would rather see a note that this is not
the original Vim but a modified version. But I suppose I can't require
that without becoming GPL-incompatible...
