New submission from Nick Coghlan <ncogh...@gmail.com>:
test_curses fails for me by default (running on Fedora 35 in KDE's Konsole):
```
[ncoghlan@thechalk cpython]$ echo $TERM
xterm-256color
[ncoghlan@thechalk cpython]$ ./python -m test -u curses test_curses
0:00:00 load avg: 0.88 Run tests sequentially

```
The active terminal info indicates that the default text colour is indeed
bright white (assuming I'm reading the infocmp output correctly), so it feels
like (15, 0) is just missing from the set of permissible "old" colour pairs in
the test case:
```
[ncoghlan@thechalk cpython]$ infocmp -L | grep initialize_color
initialize_color=\E]4;%p1%d;rgb\072%p2%{255}%*%{1000}%/%2.2X/%p3%{255}%*%{1000}%/%2.2X/%p4%{255}%*%{1000}%/%2.2X\E\,
```
