     * FIXME!
     *  This shouldn't be relying on a naive line count to decide where
     *  to start and stop because curses_message_win_puts() combines short
     *  lines.  So we can end up with blank lines at bottom of the message
     *  window, missing out on one or more older messages which could have
     *  been included at the top.  Also long messages might wrap and take
     *  more than one line apiece.
     *
     *  3.6.2 showed oldest available N-1 lines (by starting at
     *  num_mesages - 1 and working back toward 0 until window height was
     *  reached [via index 'j' which is gone now]) plus the latest line
     *  (via toplines[]), rather than most recent N (start at height - 1
     *  and work way up through 0).  So it showed wrong subset of lines
     *  even if 'N lines' had been the right way to handle this.
