So a user (or script) can just do

        tsize() { set -- $(stty size); rows=$1 cols=$2; }
        trap tsize WINCH
        tsize

Scripts could always do this with LINES and COLUMNS. The OG way is to use
something like this:

tsize() { eval `resize -u`; }
trap tsize WINCH
tsize

This is what we all used to use in the earlier X11 days. `resize' gives
you output like

$ resize
COLUMNS=80;
LINES=30;
export COLUMNS LINES;
