Summary: urllib ftp broken if Win32 proxy

Initial Comment:
If Win32 has a proxy enabled, ftp urls will NOT work in
urllib.

Here is a trace:
Traceback (most recent call last):
  File
"C:\Python22\lib\site-packages\Pythonwin\pywin\framework\scriptutils.py",
line 301, in RunScript
    exec codeObject in __main__.__dict__
  File "C:\Python22\Lib\urllib.py", line 1457, in ?
    main()
  File "C:\Python22\Lib\urllib.py", line 1448, in main
    test(args)
  File "C:\Python22\Lib\urllib.py", line 1410, in test
    fn, h = urlretrieve(url, None, reporthook)
  File "C:\Python22\Lib\urllib.py", line 80, in urlretrieve
    return _urlopener.retrieve(url, filename,
reporthook, data)
  File "C:\Python22\Lib\urllib.py", line 210, in retrieve
    fp = self.open(url, data)
  File "C:\Python22\Lib\urllib.py", line 178, in open
    return getattr(self, name)(url)
  File "C:\Python22\Lib\urllib.py", line 438, in open_ftp
    host, path = splithost(url)
  File "C:\Python22\Lib\urllib.py", line 944, in splithost
    match = _hostprog.match(url)
TypeError: expected string or buffer

If the Win32 proxy is removed, it resumes working. In
urllib splithost, url is None or an empty tuple
(instead of the actual url.)

To reproduce, just enable a proxy on Win32 and execute
the "urllib.py -t" selftest. Disable the proxy and it
will be restored.

I haven't got the setup to check if web_proxy or
ftp_proxy on Posix machines causes the same problem.
