[xmonad] [patch]

Hi Here is a small patch that was useful to me. I noticed too late that I had put non-ASCII text (UTF-8) in my patch comment. I have no experience with Darcs, so I didn't try to amend it. Darcs' send comand did not handle it well: it converted everything to single bytes characters. I edited the comment, but feel free to remove non-ACSII from the patch. Regards -- François Gannaz
