Typo in error message about ScopedTypeVariables

When I compile this code:

silly :: [a] -> [a]
silly lst = case lst of
  [] -> []
  ((h :: ty) : t) -> (h : t)

I get this error message:

    Illegal type signature: `ty'
      Perhaps you intended to use -XScopedTypeVariable
    In a pattern type-signature

It seems this should be corrected to ScopedTypeVariables
