    That's because of "\\`\\*Customiz.*\\*\\'" in same-window-regexps.
    Maybe same-window-regexp should be weakened a little so it doesn't
    force a buffer to be displayed a second time if it's already shown
    in some other window.

I think that change would cause problems for other commands,
which are defined to display a certain buffer in the selected window
and do so by means of same-window-buffer-names or same-window-regexps.
For instance, C-x m would not work right any more.
