Bizarre Haddock formatting on Hackage

[tomjaguarpaw]

On Hackage, the doc for data Nullable a says

Only used within a Field_, to indicate that it can be NULL. For example, a Field_ (Nullability SqlText) can be NULL but a Field_ SqlText cannot.

whereas if you click through to the source the comment text is

-- | Only used within a 'Column', to indicate that it can be @NULL@.
-- For example, a 'Column' ('Nullable' @SqlText@) can be @NULL@ but a
-- 'Column' @SqlText@ cannot.

I've no idea what's going on there. (The link to #Nullable is also wrong. It should be to the type constructor, not the data constructor.)
