Whoops! Yes, a CRLF in QP encoding without a preceding equal sign is a hard line break.

An e-mail messages is a sequences of lines terminated in CRLF; the client and server software is permitted to replace the two terminating characters with whatever is appropriate for the OS. A MIME part with QP (bletch!) encoding uses =CRLF for a soft break; that is, it does not represent CRLF in the unencoded text. A CRLF not preceded by an equal sign is a soft break; it represents a CRLF in the unencoded text. A message with format=flowed in the Content-Transfer-Encoding header field uses SP CR LF for a soft break and a CRLF not preceded by a space for a hard break. Note that the last two cases are both MIME. -- Shmuel (Seymour J.)
