This matches what I remember of randr.  I'm pretty happy to see such
a patch that has good chances to make it in the repo - and even trigger
a new release.

However I'd like people who actually have multiple screens setups to
*test this and report back*.  I have never used ratpoison with multiple
screens, I don't have multiple screens at hand and I don't want to make
assumptions about the changes that might affect users. :)

Thanks,
