[Python-3000] lib2to3 refactor.py has a lot of 2.6-isms

[Raymond Hettinger]

The intended upgrade path is through 2.6.
If you go straight from 2.5, you don't get
to go through a step with the -3 warnings
and optional text/bytes annotations.

IMO, it would be a mistake to create a 2.5 to 3.0 converter.
