Elaborate on what?  The screw-up is that certain operations do not
work right on ptys.  A streams-based implementation of "script" was
sent to me by Norman Wilson; it consisted of a few lines of shell
script.  The only thing not working was signal propagation to the
correct process group, because the Bourne shell doesn't have a way
to manipulate that.  A translation to C would also be only a few
lines and could solve the signal problem.
