bug#9419: 24.0.50; C-x k deletes the entire frame instead of switching to another buffer

[Eli Zaretskii <eliz@gnu.org>]

This bug report will be sent to the Bug-GNU-Emacs mailing list
and the GNU bug tracker at debbugs.gnu.org.  Please check that
the From: line contains a valid email address.  After a delay of up
to one day, you should receive an acknowledgement at that address.

Please write in English if possible, as the Emacs maintainers
usually do not have translators for other languages.

Please describe exactly what actions triggered the bug, and
the precise symptoms of the bug.  If you can, give a recipe
starting from `emacs -Q':

 emacs -Q
 M-x list-colors-display RET
 C-x 1
 C-x 5 b *Colors* RET
 C-x b foo RET
 C-x b *Colors* RET
 C-x k

Boom! the frame is deleted, although there's at least one more buffer
(`foo') in that frame's nuffer list.

This happens because window-deletable-p returns `frame' for the window
of the *Colors* buffer.  It does so because that buffer's window's
quit-restore parameter has `new-frame' as its car.  Why is that so, I
don't know; quit-restore doesn't seem to be documented anywhere, only
mentioned in a few doc strings without any explanation.  Perhaps the
reason is that *Colors* was the first buffer on that frame?

If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.
For information about debugging Emacs, please read the file
