Summary
  • DO NOT QUEUE THIS **

I have no idea how this is supposed to be fixed for real, but it's likely
related to the comment above where stdout is set about maybe needing a silly
wrapper. PEP 528[1] talks about not assuming the encoding of sys.stdout.buffer,
but I thought the whole point of always using bytes was to avoid encoding.

This hack allows TortoiseHg to work when built with py2exe on py3, by avoiding
this:
