Thanks for the report. Fixed in CVS.

Text.PrettyPrint.HughesPJ has a hook for this and more (Style), but it
wasn't exported by Language.Haskell.Pretty. I don't think it belongs
in PPHsMode, because those are parameters that govern the conversion of
a syntactic object into a Doc, while Style governs the conversion from
Doc to String. I've added a new function prettyPrintStyleMode that
takes both parameters.
