Actually Haddock attaches instance information to the modules in a
separate step after having processed all of them. The fact that no
documentation shows up for instances under the class documentation is
a bug, embarrasingly enough, which I hadn't noticed. Looking at the
code, it's not that I've forgotten to add code to the Html backend,
it's something deeper that is wrong, so I will have to investigate.
