Formatting/saving a file with parse errors opens up Output pane and steals cursor focus

[samuela]

I save pretty frequently and anytime I save a haskell file that has any sort of parse error in it, the style-haskell Output pane (from the bottom) opens itself up and takes away the focus from the main text editor. It says

Language.Haskell.Stylish.Parse.parseModule: could not parse <unknown>: ParseFailed (SrcLoc "<unknown>.hs" 72 1) "Parse error: ;"

and this gets really annoying since it happens on almost every save.
