Comment (by duncan):

 And of course we have the same problem with `{-# OPTIONS -fglasgow-exts
 -cpp #-}` which is generated by `alex`. So even if you didn't realise you
 use `CPP`, if you use `alex` then you do and then haddock fails because we
 don't run `cpp` on that file. So if we go looking for `LANGUAGE` pragmas
 then we'd also have to do the same for `OPTIONS` (and `OPTIONS_*`)

 Seems that `getOptionsFromSource` gets those too which is nice. Perhaps we
 should just do that for every file in builds and when haddocking.
