Comment:

 So here's the initial version of the patches. Everything compiles and
 validates.
 As for Haddock, in a few places I'm not sure if I'm not breaking anything;
 I've
 added small FIXME notes in such places. Anyway, let me know if there's
 anything
 that could be improved.

 Btw. what is the recommended way of getting the Haddock patch merged?
 Should it
 go through upstream? Currently the git repo distributed with GHC contains
 a few
 more patches/changes than the darcs one..
