Function xo_humanize

* A wrapper for humanize_number that autoscales, since the * HN_AUTOSCALE flag scales as needed based on the size of * the output buffer, not the size of the value. I also * wish HN_DECIMAL was more imperative, without the <10 * test. But the boat only goes where we want when we hold * the rudder, so xo_humanize fixes part of the problem. */
