I agree with Wolfgang on this:  you simply can't tell from the system
set-up whether it supports the hardware, i.e. whether the terminal
Does the Right Thing with eight bit characters or not. If you're using
a dumb character terminal as well as a smart terminal on the same system
you definitely need the run-time option.  In any case, there's no
way of deciding automatically and (as Uli has been saying) these NEXTSTEP
people like the thing just to work.  Configuring at compile-time whether
to dump raw characters at run-time to a terminal which could be anything
is just too brutal.  (What you possibly could configure is whether or not
to compile in the *option*, but I think it's obvious that that has less
than welcome side effects for code.  More plausibly you could decide at
compile time system by system whether the option should be in effect by
default.)

that was stupid... I simply noticed the last two were out of order and
thought therefore I could dump the new one on the end.  Here's a revised
version.
