  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

Issue 8547 - detecting and reporting that modules have been imported from the wrong location under test discovery.

chunk larger than 1GB with the zlib module's compressor and decompressor
objects.

adds handle_error(self):raise to test modules using asyncore to provide a clearer error message in case something goes wrong

Fix asyncore issues 8573 and 8483: _strerror might throw ValueError; asyncore.__getattr__ cheap inheritance caused confusing error messages when accessing undefined class attributes; added an alias for __str__ which now is used as a fallback for __repr__

out as it is currently unneeded.

Describe ElementTree 1.3; rearrange new-module sections; describe dict views as sets; small edits and items

Removed various unused code and added a way to correctly determine
server vs. workstation via the registry.

never remember the default port number it uses...)

Fix some more functions by hand

Run Antoine Pitrou "untabify" script + manual editions (OS/2 and some
