Change rendering of duplicate record field docs
See Haddock Trac #195. We now change this behaviour to only rendering
the documentation attached to the first instance of a duplicate field.
Perhaps we could improve this by rendering the first instance that has
documentation attached to it but for now, we'll stick with this.
