62	Haddock forgets that modules are hidden	igloo		"With `src/A.hs`:
{{{
{-# OPTIONS_HADDOCK hide #-}

module A where

a = 'a'
}}}
and `src/B.hs`:
{{{
module B where

import A

b = 'b'
}}}
and the haddock in GHC's HEAD I get:
{{{
$ cd src
$ haddock --html A.hs B.hs -D foo.haddock
$ grep A.html index.html
$ grep B.html index.html
><A HREF=""B.html""
$ cd ..
$ haddock --gen-index --gen-contents -o . --read-interface=foo,src/foo.haddock
$ grep A.html index.html
><A HREF=""foo/A.html""
$ grep B.html index.html
><A HREF=""foo/B.html""
$
}}}
i.e. when we tell haddock to generate contents and index pages it doesn't know that some modules should be hidden. This is bad, because `A.html` doesn't exist.
