This and the protocol patch both look good to me; in particular I
(surprisingly) can't see a problem with the versioning! The one thing
it's missing though, is integration into clients/window.c where it
sets up the keyboard repeat, inside keyboard_handle_key. That aside,
I think this is good for merging.
Thanks :)
