Merge p3yk branch with the trunk up to revision 45595. This breaks a fair
number of tests, all because of the codecs/_multibytecodecs issue described
here (it's not a Py3K issue, just something Py3K discovers):
http://mail.python.org/pipermail/python-dev/2006-April/064051.html

Hye-Shik Chang promised to look for a fix, so no need to fix it here. The
tests that are expected to break are:

test_codecencodings_cn
test_codecencodings_hk
test_codecencodings_jp
test_codecencodings_kr
test_codecencodings_tw
test_codecs
test_multibytecodec

This merge fixes an actual test failure (test_weakref) in this branch,
though, so I believe merging is the right thing to do anyway.

+
+The result objects from the \function{urlparse()} and
+\function{urlsplit()} functions are subclasses of the \pytype{tuple}
+type.  These subclasses add the attributes described in those
+functions, as well as provide an additional method:
+
+\begin{methoddesc}[ParseResult]{geturl}{}
+  Return the re-combined version of the original URL as a string.
+  This may differ from the original URL in that the scheme will always
+  be normalized to lower case and empty components may be dropped.
+  Specifically, empty parameters, queries, and fragment identifiers
+  will be removed.
+
+  The result of this method is a fixpoint if passed back through the
+  original parsing function:
+
+\begin{verbatim}
+>>> import urlparse
+>>> url = 'HTTP://www.Python.org/doc/#'
+
+>>> r1 = urlparse.urlsplit(url)
+>>> r1.geturl()
