<div dir="ltr">Great, last question. Is the environment variable COLUMNS the # of columns or the width of the terminal window? My terminal doesn't set that env variable so I can set it manually to test but not sure what the usage normally is.<br>

</div>The environment variable should change when your terminal window<br>
changes, so using the variable would work in both cases. Using the<br>
terminal window size as a fallback in case the environment variable is<br>
bogus or unset would be a good idea.<br>
