Average just takes the number of entries in a group, and divides the total by
the count. Here's the implementation:

  OPTION_(report_t, average, DO() { // -A
      OTHER(empty).on(whence);
      OTHER(display_total_)
        .on(whence, "count>0?(display_total/count):0");
    });

Which means that `--average` is just a short-hand for:

  --empty --display-total "count>0?(display_total/count):0"
