    #5610: use \Z not $ so we don't eat extra chars when body part ends with \r\n.

    If a body part ended with \r\n, feedparser, using '$' to terminate its
    search for the newline, would match on the \r\n, and think that it needed
    to strip two characters in order to account for the line end before the
    boundary.  That made it chop one too many characters off the end of
    the body part.  Using \Z makes the match correct.

    Patch and test by Tony Nelson.
