Update of /cvsroot/python/python/dist/src/Lib/email In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv3223

Modified Files: FeedParser.py Log Message: readline(): RFC 2046, section 5.1.2 (and partially 5.1) both state that the parser must recognize outer boundaries in inner parts. So cruise through the EOF stack backwards testing each predicate against the current line.

There's still some discussion about whether this is (always) the best thing to do. Anthony would rather parse these messages as if the outer boundaries were ignored. I think that's counter to the RFC, but might be practically more useful. Can you say behavior flag? (ug).
