POSIX bashing

Well, I suspect that's what some *are* proposing - either linking it
into every application (although perhaps doing so dynamically, and
transparently, so that anybody who does a cooked-mode "read()" from a
tty gets the data passed through that code), or sticking it in front of
the tty as a pty-based front end.

I'm not sure *I* wouldn't want it.  Most of the cooked-mode typing I do
is to a shell, and I found it not to be a real problem to have a whizzy
editor only in "ksh".  Maybe it wouldn't be a problem having "ksh"s
input editing code in wired-down kernel code, and maybe it wouldn't be
wired down, but....
