Exactly - but AIUI, encoded body parts are canonicalised during SMTP,
just like unencoded text parts.  Correct me if I'm wrong, but the
"foo\nbar" above will be received as "foo\r\nbar" and the receiver
_may or may not_ convert that back to "foo\nbar" (depending on the
recipient's local conventions).  But if "foo=0a=\nbar" is
canonicalised to "foo=0a=\r\nbar", it still decodes to "foo\nbar",
since "=\r\n" is ignored (the same as "=\n").  Does that make any kind
of sense?

Perhaps this is a topic to bring up in comp.mail.mime?
