That's because it's March now. The bug shows up when today's date is in
the 3-month period centered around December.

Basically, after calling calendar-other-month you still need to call
calendar-cursor-to-visible-date.

      (if (and (= arg 1)
               (calendar-date-is-visible-p jan-first))
          (calendar-cursor-to-visible-date jan-first)
        (calendar-other-month 1 (- year (1- arg))))))
