curses vs !HILITE_STATUS

curses vs !HILITE_STATUS

The curses interface wouldn't build with HILITE_STATUS disabled.  I
started adapting it to handle genl_status_update() but that was taking
too much effort with each niggling detail leading to another.  This
goes the opposite direction:  forcing the old STATUS_VIA_WINDOWPORT
behavior without having that #define available.  That dragged along a
bunch of unexpected changes too.
