I was basing it on that there hasn't been a release with xmonad.hs, and
darcs users get what they ask for (and it's a pretty easy transition).
Recall, for instance, the removal of the existential Layout constructor.
I also wasn't sure if dons/sjanssen were leaning more towards -i, so I
didn't put any extra effort into it.
