Thanks for all the suggestions in this thread.  I've created three tickets:

   http://hackage.haskell.org/trac/hackage/ticket/104
   http://hackage.haskell.org/trac/hackage/ticket/105
   http://hackage.haskell.org/trac/hackage/ticket/106

and fixed the easy bug (no. 2 above).

Maybe we'll get a chance to hack on some of these during Hac, but there's an 
awful lot of tickets there...

Cheers,
