------------------
- get_header(): Fix up RFC 2047 encoded words separated by 'CRLF LWSP' (which is fine according to the RFC) by replacing the CRLF with a SPACE so decode_header can parse them correctly. This works around a bug in decode_header that has been fixed in 3.3. See http://bugs.python.org/issue4491 and its duplicate. [lgraf]
2.3.2
------------------
- Make RegEx for Apple Partial Encoding regex more specific so we don't accidentally remove quotes around header parts that need them. [lgraf]
- Added test for zip export. [lknoepfel]
