bug#68679: 30.0.50; Burying a buffer shows an already displayed buffer

[Sam Steingold]

ISTR that quit-window and bury-buffer made sure that the
replacement/newly displayed buffer is not shown in any other window (at
least that was my intention when I wrote quit-window many years ago).

Right now I see that C-x b (switch-to-buffer) offers a good candidate
(IOW, other-buffer returns a buffer that is not currently shown), but
both quit-window and bury-buffer replace the current buffer with one
that is already displayed in another window in the current frame.

Is there a way to restore the original behavior of never displaying an
already visible buffer?

Is this a (known) bug?

Thank you!
