[xmonad] darcs patch: clarify comment at top of Config.hs

We'll have to remember to change xmonad.hs to config.hs in the comments, if/when that happens. Sun Nov 11 14:13:04 EST 2007 Devin Mullins <me@twifkak.com> * clarify comment at top of Config.hs There appears to be some confusion -- several people have wanted to edit Config.hs as was done in the past. This comment probably won't stop that, but it's a start.
