    What does the copper pointer and the scaled piece over which it
    travels control? The scale has the word "longer" stamped into it, but
    it's not clear to me exactly what effect it has on the operation of
    the thermostat.

    That is called the heat anticipator, and yes..it does indeed effect the
    stat.
    You set the anticipation setting to that setting that the furnace states,
    and leave it alone. It influences the spring stat and will prevent your
    furnace from overshooting, or short cycling.
