for form field values.

IOError, keep the traceback.

Fix 1: add a method geturl() to the file-like object returned by urlopen().
Fix 2: treat http error 301 the same as error 302.

Correctly handle a URL containing user:password@host when using a proxy.

is forgiving about semi-numeric port numbers, and allows you to specify
a default port (default is -1, None returned for nonnumeric port).

to specify where it should go (if specified, even local files will be
copied into the given file).

(Proxy handling uses <proto>_proxy environment variables by default.)

mac, so far)

- basejoin('some/url', '#name') would strip the last component of
  some/url and resturn some/#name.
- basejoin('file.html', 'relative/path') would return something like
  file:/relative/path, making a relative path into an absolute one.
These bugs are fixed by some drastic changes.  No scheme is added when
none is present (i.e. it works as replacement for posix.joinpath).
If a scheme is present in the second argument, it is returned
unprocessed.  No hostname are added in this case.  If no scheme is
present, the scheme of the first argument, if present, is used.
The algorithm is commented profusely.
Also fixed a typo in a comment.

If code keeps a reference to self.fp or any of its methods, you don't
want to close self.fp just because no explicit reference is kept to self.

	* Lib/traceback.py: print SyntaxError correctly
	* Lib/stat.py: moved to posixstat.py; added macstat.py which has
