What do you mean?  They both catenate onto one stream of bytes, it
shouldn't matter where the flush boundaries are...

It so happens as a convenient property of the textual modes is that
adding more payload is purely concatenative (not true for binary,
where there's a header that would cause confusion to the receiving
side)
