I can't think of an actual real world regression.  I could have said
"error introduced by" or something?  It only fixes the case where
the ioctl(fd, TIOCGWINSZ, &ws) fails for some reason - we would
end up thinking the screen had some very large number of lines.

(I only noticed this as I was copying the code)
