Fixes #607789, bugfix candidate.

Jeremy reported that this is not allowed by RFC 2396; however,
other tools support unescaped @'s so we should also.

Apply SF patch 596581 closing bug 581529.

the recommended ones.

Do not mention the string module in the rlcompleter docstring.

This partially applies SF patch http://www.python.org/sf/562373
(with basestring instead of string). (It excludes the changes to
unittest.py and does not change the os.stat stuff.)

When os.stat() for a file raises OSError, turn it into IOError per
documentation.

This change is similar to the supplied patch, but does not save the opener
when a proxy configuration is specified.
This closes SF patch #523415.

Bugfix candidate (this and the previous checkin, obviously).

I really can't test this, but from reading the discussion in that bug
report, it's likely that this works.  It may also close a whole bunch
of other bug reports related to urllib and proxies on Windows, but who
knows.

open_http():
    In urllib.py library module, URLopener.open_https()
    returns a class instance of addinfourl() with its
    self.url property missing the protocol.

    Instead of "https://www.someurl.com", it becomes
    "://www.someurl.com".

Modify rfc822.formatdate() to always generate English names,
regardless of locale.  This is required by RFC 1123.

In open_local_file() of urllib and urllib2, use new formatdate() from

Look specific to Windows.  Don't know whether it works.

  For local files urllib.py doesn't return the MIME
  headers that the documentation says it does:

  http://www.python.org/doc/current/lib/module-
  urllib.html#l2h-2187 states that "When the method is
  local-file, returned headers will include a Date
  representing the file's last-modified time, a Content-
  Length giving file size, and a Content-Type containing
  a guess at the file's type"

  But in Python 2.1 the only header that gets returned
  is the Content-Type:

  >>> import urllib
  >>> f = urllib.urlopen("gurk.txt")
  >>> f.info().headers
  ['Content-Type: text/plain\n']

This closes SF patch #419459.
