This is already merged as well.

The current version simply fails to transmit the messages in case the
length of a buffer is 0. I have patch ready to make it work with the
proposed spec changes, just waiting for them to be accepted.

It doesn't break anything for now since we don't have much users and
we know zero length transfers don't work. I will submit the necessary
changes once spec is finalized.
