Describe the bug
Multiline Haddock comments are "normalized" away. This does not happen for normal multline comments.

To Reproduce

module Test where

{- This is fine
-}

{- | This is not
-}
hello :: Int
hello = 1

Output:

module Test where

{- This is fine
-}

-- | This is not
hello :: Int
hello = 1

Expected behavior

Multiline Haddock comments should stay multline.
