The documentation of function arguments is not rendered correctly

[basvandijk]

If I add haddock documentation to the arguments of a function they are not rendered correctly. For example:

foo :: a -- ^ the @a@ argument
    -> b -- ^ the @b@ argument
    -> c -- ^ the @c@ argument
    -> d

is rendered wrongfully as:

foo
:: 	
=> a	the b argument
-> b	the c argument
-> c	
-> d	

(Note that I'm using haddock-2.6 but I can't select that version for this ticket)

I just discovered that when you explicitly quantify the type variables in the type the documentation is rendered correctly. For example:

foo :: forall a b c d
    .  a -- ^ the @a@ argument
    -> b -- ^ the @b@ argument
    -> c -- ^ the @c@ argument
    -> d

is rendered correctly as:

foo
:: forall a b c d . 	
=> a	the a argument
-> b	the b argument
-> c	the c argument
-> d

We recently fixed this. Thanks for the report though - I updated the test case to cover your example.
