Ticket: http://hackage.haskell.org/trac/ghc/ticket/4880

This proposal adds missing instances for the two newtype wrappers for Maybe in Data.Monoid. A patch is attached to the ticket. Both the motivation and implementation are straightforward.

Discussion period: 2 weeks (until 20 Jan 2011).

Cheers,
Sterl
