The version seen in py3k is the intended formatting; I don't remember
anything about a change, but given the time I've not had in following
commit messages and discussions, I could easily have missed something.

I'm strongly in favor of the output from the Python 3.0 version; the 2.6
version is silly, even if you're not already laughing at the indent
parameter.

(When I first wrote pprint, I was working with huge nested tuples, for
which I found the indentation control useful.  Haven't used it since,
though I suspect that's the sort of thing that makes others try it out.)
