-From the outset,
-\fI\%ncurses\fP used \fBnl\fP/\fBnonl\fP to control the conversion of
-newlines to carriage return/line-feed on output as well as input.
-XSI Curses documents only the use of these functions for input.
-This difference arose from converting the \fIpcurses\fP source
-(which used \fBioctl\fP calls with the \fBsgttyb\fP structure)
-to termios (i.e., the POSIX terminal interface).
-In the former, both input and output were controlled via a single
