It has been a long time since I wrote this. If I recall correctly, the
purpose of this was to get the width of the terminal, which apparently
does not work inside emacs. The fix is probably to deal with zero output
correctly, probably just forcing it to use the parts of the code where
it defaults to some fixed width if it can't figure out how wide it
should be.
