My experience is that you can never be well defended against mixing
signed with unsigned.
Stefan and Chong, please voice your opinions about this. I'm strongly
opposed to having the last argument of emacs_read and emacs_write be
of unsigned data type, but if you are okay with that, I'll get over
it.

Those hurt feeling would have been avoided if you waited until the
discussion is over and decision is made.
