resize requires having a terminal type that actually does xterm-style
answerback, which as at best a "maybe".

What you *really* want is the output of stty:
$ stty -a |grep rows
speed 38400 baud; rows 56; columns 144; line = 0;

because it's a property of the tty, and changed there - putting the
values in the environment is an old and not-really-workable hack.
