I don't understand this comment (you seem to be saying that because there
is some reluctance to install a working version of ncurses, that there's
no reason to use packages which use it).

not very old at that point (iirc, it dates to the late 70's, and was still
considered "new" when I encountered it in 1983)

as I understand it, most of the "NCurses extensions" you refer to are
standard in SVr4 curses (color, function keys).

that's a different problem (libreadline doesn't mix with curses on any
system because it makes incompatible assumptions about terminal initalization).
