FWIW, the change that Gerd suggests should make things faster rather
than slower (it doesn't change the mount of bytes sent, only the number
of `write` we perform).  The risk is that it bumps into a bug where
sending text in too-large a chunk leads to some error, as it seemed it
was the case in some `telnet` cases back before 1991.
