    It's a good try. But there are some important things missing from
    this patch -- notably the Textpad class, which is needed for doing
    popup queries correctly.

    Also, arrow keys don't work under the curses implementation linked
    with in Red Hat's python1.5. This is a symptom of a deeper problem,
    which is that older Pythons link the Berkeley curses library rather
    than ncurses.

    Clicking on a URL link with bomb xconfig with this patch under 1.5. You
    didn't handle `import webbrowser' failure. Easy thing to miss.

    I personally added the ncurses/Textpad/ascii features to the Python
    libraries shipped in 2.0, and I did it for a reason -- to support what
    `make menuconfig' needs. Backporting to 1.5.2 is only going to give a
    partial, ugly subset of menuconfig. I don't think it's good enough.
