darcs patch: rewrite of Distribution.Simple.Haddock (and 1 more)

Thu Feb 19 16:37:38 CET 2009 Andrea Vezzosi * rewrite of Distribution.Simple.Haddock In addition to (hopefully) making clear what's going on we now do the additional preprocessing for all the versions of haddock (but not for hscolour) and we run cpp before moving the files. Mon Mar 2 02:51:37 CET 2009 Andrea Vezzosi * use -D__HADDOCK__ only when preprocessing for haddock < 2 haddock-2.x doesn't define any additional macros.
