If the pretty printer honors the existing whitespace and adds its own
indentation then repeated application, i.e., in -> pp(in) -> pp(pp(in))
etc, should increase indentation but it doesn't: in and pp(in) may be
different but after that it's a no-op. Why? Clearly I don't have a good
mental model of how the transformer works.
