        The MS-Windows port of ncurses fails to switch to a color pair if
        one or both of the colors are the implicit default colors.  This
        change records the default colors when TUI is initialized, and
        then specifies them explicitly when a color pair uses the default
        colors.  This allows color styling in TUI mode on MS-Windows.
