Blocked revisions 85322,85326 via svnmerge ........ r85322 | r.david.murray | 2010-10-08 11:55:28 -0400 (Fri, 08 Oct 2010) | 8 lines #4661: add bytes parsing and generation to email (email version bump to 5.1.0) 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. ........ r85326 | r.david.murray | 2010-10-08 17:37:39 -0400 (Fri, 08 Oct 2010) | 2 lines What's new entry for email 5.1. ........
