Looking at what handle_body() does for TE_BASE64 and TE_QP cases, I have
to wonder if this is enough.  The loop seems to stop at (*op == NUL) which
follows an old assumption that each line is terminated with NUL, not the
new assumption you introduced that each line's length is kept in local
variable len.
