\case should trigger auto-multiline mode in ghci

In ghci, most block heralds trigger the multiline mode when :set +m is on. However, \case does not (and should). Compare:

Prelude> ($True) (\case
Prelude|  x -> x
Prelude| )
True
Prelude> ($True) $ \case

<interactive>:11:11:
    Empty list of alternatives in case expression
      Use EmptyCase to allow this
