/*AT&T
AT&T With the idlok() routine, if enabled (bf is TRUE), curses conciders
AT&T using the hardware insert/delete line feature of terminals so equipped.
AT&T If disabled (bf is FALSE), curses very seldom uses this feature.
AT&T This option should be enabled only if the application needs
AT&T insert/delete line, for example, for a screen editor.
AT&T It is disabled be default because insert/delete line tends to be
AT&T visually annoying when used in applications where it isn't really
AT&T needed.  If insert/delete line cannot be used, curses redraws the
AT&T changed portions of all lines.
