I think it would preferable to use terminfo or termcap directly for
this. The former exists at least on every system with ncurses and NetBSD
6+, the latter on another range of systems. All curses implementations I
am aware of pull one of those two libraries in, but add more junk on
top. I don't see any need for supporting termcap for optional colour
support, so just going with terminfo sounds fine.
