  #1858 from Tarek Ziade:
  Allow multiple repositories in .pypirc; see http://wiki.python.org/moin/EnhancedPyPI
  for discussion.

  The patch is slightly revised from Tarek's last patch: I've simplified
  the PyPIRCCommand.finalize_options() method to not look at sys.argv.
  Tests still pass.

  Cleaned up io._BytesIO.write().

  worked. Who wrote that thing? Oh, it is me... doh.
