[xmonad] Changing module headers

[Adam Vogt]

You could strip comments with something like this. The results might be 
slightly better, depending on how well sim works. Haskell-src-exts is 
improving, but it still fails on a couple modules in contrib.

#!/usr/bin/env runghc

> import System.Environment
> import Language.Haskell.Exts
> import Control.Monad

> main = mapM_ (putStrLn . prettyPrint . fromParseResult <=< parseFile) =<< getArgs
