Thanks for the patch (and the clarifications).  But I feel uneasy about
changing a general function to cater to the specific needs of todo-mode,
unless it is certain that the change would not cause problems for other
existing uses.  This unease prompted me to look at todo-quit again, and
it turns out that replacing bury-buffer there by quit-window DTRT as
described above.  So I will make that change and there's no need to
change bury-buffer.  This should also mean the existing test will work
again without change (I'll confirm with `make check' before pushing).
(I had taken over the invocation of bury-buffer in todo-quit from the
old first version of todo-mode.el, which I believe predates the
introduction quit-window, and till now had not second-guessed its use.
Better late than never.)

Thanks for the feedback.
