I'm able to reproduce the GNU behavior on 9.0-CURRENT which is IMO right.

I think we need to break at the line end to provide better interactivity
(the current code seems to do it (buffer is not full && !eof), while
what we wanted is (buffer is not full && !eof && !eol).

The attached patch should fix this but I have not yet thoroughly tested
it due to job work.
