Documentation of atomicModifyMutVar# does not show properly

The actual documentation in the source is:

-- | Modify the contents of a @MutVar\#@. Note that this isn\'t strictly
--      speaking the correct type for this function, it should really be
--      @MutVar# s a -> (a -> (a,b)) -> State# s -> (# State# s, b #)@, however
--      we don\'t know about pairs here. 

It actually shows as this in the docs, note the incomplete signature:

Modify the contents of a MutVar#. Note that this isn't strictly speaking the correct
type for this function, it should really be MutVar s -> ( s, b #), however we 
don't know about pairs here.
