This commit also restores the news item for 167256 that it looks like
Terry inadvertently deleted. (Either that, or I don't understand
now merging works...which is equally possible.)
This patch also deprecates the MalformedHeaderDefect. My best guess is that
this defect was rendered obsolete by a refactoring of the parser, and the
corresponding defect for the new parser (which this patch introduces) was
overlooked.
This patch primarily does two things: (1) it adds some internal-interface
methods to Policy that allow for Policy to control the parsing and folding of
headers in such a way that we can construct a backward compatibility policy
that is 100% compatible with the 3.2 API, while allowing a new policy to
implement the email6 API. (2) it adds that backward compatibility policy and
refactors the test suite so that the only differences between the 3.2
test_email.py file and the 3.3 test_email.py file is some small changes in
test framework and the addition of tests for bugs fixed that apply to the 3.2
API.
There are some additional teaks, such as moving just the code needed for the
compatibility policy into _policybase, so that the library code can import
only _policybase. That way the new code that will be added for email6
will only get imported when a non-compatibility policy is imported.
This new interface will also allow for future planned enhancements
in control over the parser/generator without requiring any additional
complexity in the parser/generator API.
Patch reviewed by Éric Araujo and Barry Warsaw.
The work on this is not 100% complete, but everything is present to
allow real-world testing of the code. The only remaining major todo
item is to (hopefully!) enhance the handling of non-ASCII bytes in headers
converted to unicode by RFC2047 encoding them rather than replacing them with
'?'s.

#5610: use \Z not $ so we don't eat extra chars when body part ends with \r\n.
If a body part ended with \r\n, feedparser, using '$' to terminate its
search for the newline, would match on the \r\n, and think that it needed
to strip two characters in order to account for the line end before the
boundary. That made it chop one too many characters off the end of
the body part. Using \Z makes the match correct.

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.
