cursesgraphics

Not sure whether it was because I hadn't build without curses
in a long time or because of recent changes in warning settings
in the hints, but optfn_cursesgraphics() first drew a complaint
about lack of prototype, then after I added one and made it be
static, about a static routine not being used.
