haskell-src-exts [1] is probably as pretty as you get, but it doesn't
differ much at all from haskell-src in its output. I'd be happy to
have any specific complaints about it reported on my trac [2] though,
I'm always keen to improve the product, and if you make your voice
heard then chances are quite good that you get your wish. :-)
