Serious Haddock bug

[Neil Mitchell]

Hi,

I found a fairly serious Haddock bug: http://trac.haskell.org/haddock/ticket/69

It causes GHC's documentation to go wrong
(http://hackage.haskell.org/trac/ghc/ticket/2894#preview), Hoogle to
break (http://code.google.com/p/ndmitchell/issues/detail?id=101) and
will effect Hackage before too long. It certainly causes "even" to be
missing from the library documentation, but I have no idea what else
it causes to go incorrect.

Since the information runs the risk of being strewn around different
bug trackers, I thought I'd email so everyone can try and keep track
of it.

Thanks

Neil
