    Don't transform imports that are already relative.  2to3 turned
      from . import refactor
    into
      from .. import refactor
    which broke the transformation of 2to3 itself.

    Make 2to3 run under Python 2.5 so that the benchmark suite at
    http://hg.python.org/benchmarks/ can use it and still run on implementations
    that haven't gotten to 2.6 yet.  Fixes issue 8566.
