[haddock @ 2005-01-15 18:44:45 by panne]

Make Haddock compile again after the recent base package changed. The Map/Set
legacy hell has been factored out, so that all modules can simply use the new
non-deprecated interfaces. Probably a lot of things can be improved by a little
bit of Map/Set/List algebra, this can be done later if needed.

Small note: Currently the list of instances in HTML code is reversed. This will
hopefully be fixed later.
