I have a couple of doctests that assume that pprint will sort by key,
yes.  It makes the tests look quite a bit nicer by pprinting the
output, and I get sorting (which matters for some older Pythons) for
free.  (I admit I don't actually use those tests with older Pythons,
but the principle stands.)

I don't see why we don't do the obvious, namely add the option to use
"native" order to the PrettyPrinter class, with the default being
backward compatible.
