[xmonad] darcs patch: Typo in window-properties.sh

1 patch for repository http://code.haskell.org/XMonadContrib: Wed Apr 13 01:30:02 EDT 2011 Brandon S Allbery KF8NH * Typo in window-properties.sh Somewhere between my creating the original version of this script and adding it to the tree, a backslash got lost. It appears to have been lost in the version I put on the wiki, so I suspect a copy-paste problem at that point.
