1.920     2013-06-17
          do not call parts_set during walk_parts unless the parts have
          actually changed

          When trying to decode a body, fall back to 7bit if the encoding is
          unknown.  Trying to create a new body in an unknown encoding is still
          forbidden.  This should make it easier to handle broken messages
          from "the internet."  ("Content-Transfer-Encoding: \ 
n"!?)

          try to encode headers based on the header structure, if it has one,
          rather than treating the header as a big string in all cases; thanks
          for this work go to Jesse Luehrs
