  * Add showMultiLineString to GHC.Show
  
  This is part of the fix for #4436
  
    showMultiLineString :: String -> [String]
    -- | Like 'showLitString' (expand escape characters using Haskell
    -- escape conventions), but 
    --   * break the string into multiple lines
    --   * wrap the entire thing in double quotes
    -- Example:  @breakMultiLineString "hello\ngoodbye\nblah"@ 
    -- returns   @["\"hello\\", "\\goodbye\\", "\\blah\"" ]@
    -- where those "\\" are really just a single backslash
    -- (but I'm writing them here as Haskell literals)

    M ./GHC/Show.lhs -11 +37
