Hmmm ... is this really going to be simpler or more robust than lexing
the string carefully enough to insert tabs at the right places? The
impression I had so far was that you'd only need to understand about
Python's string-literal conventions to get that right ... and that's
something that's not likely to change. I'm not so sure that parse
trees can be regarded as an immutable API.
