and in that case, i think cmdedit assumes 80 columns, which is often
correct.  but not always.

i have a tiny version of the old X11 "resize" utility that
queries the terminal for its dimensions, then tells the kernel
what they are.  it's very handy.  i can turn it into an applet if
anyone's interested.  it solves this problem (both width and
height) for vi, as well.
