I'm still not convinced that this is necessary or desirable
behaviour. I can understand the parser doing this as a
workaround before we had universal newlines, but now that
we do, I'd expect any Python string to already have newlines
converted to their canonical representation, and that any CRs
it contains are meant to be there. The parser shouldn't need
to do newline translation a second time.
