I think it is still not quite there. Since as you noted the backend
will complain if line endings don't match, if we hit EOF then we have
to cons up a \. line with the correct ending. (BTW, this is not
actually necessary when talking 3.0 protocol, but it is when talking
to an older server.)
I modified the patch a little more and applied the attached. It seems
to work for me but could use more testing.
