I've prepared the changes, but one question arises. Evil now contains
some code snippets stolen from other sources, usually from GNU Emacs
itself (I know this because I've been the thief ;)). These files are
usually distributed under GPLv3 whereas Evil still has GPLv2. For
correctness we should therefore upgrade the licensing to GPLv3, too.
Is there any problem with this (I ask all contributors)? (Otherwise
I'll simple change the "2" to a "3" in the license comments).
