bkgdset change in ncurses 6.0/5.9?

[Mengyang Li]

Hi,

 I run into a color formatting issue after I updated ncurses to 6.0 on gentoo. Here is the python snippet to reproduce the issue.

    stdscr.bkgdset(' ', curses.color_pair(1))

    stdscr.clear()

    stdscr.border()

    stdscr.addstr(1, 1, "text should be in red", curses.color_pair(2))

                                       \- this text is shown as RED in ncurses 5.9, but it's WHITE in 6.0

Is this a known issue? Or an incorrect behavior fixed in 5.9? I've read the changelog but I didn't find related change on this. Please advise.
