Hello there,I think there is a small bug with quit-window / quit-restore-window :
with emacs -Q
;; set some rules
(setq display-buffer-alist
'(("\\*\\(Backtrace\\|Messages\\)\\*"
(display-buffer-in-side-window)
(window-height . 0.2)
(side . bottom))))
;; trigger a logical error to display the *Backtrace* buffer
(> vim emacs)
;; display the *Messages* buffer
(view-echo-area-messages)
;; mess the `quit-restore' window parameter
(kill-buffer (get-buffer "*Backtrace*"))
;; which looks now like that in the *Messages* window :
;; ((quit-restore) (window-slot . 0) (window-side . bottom))
;; try to quit the *Messages* window
(progn (select-window (view-echo-area-messages))
(quit-window))
;; nothing happens :
The first `cond' of quit-restore-window end up to 't,
it calls (switch-to-prev-buffer window bury-or-kill)
but there is no previous-window available.
The first patch adress this, and a similar one : when there is a previous-buffer available, but it referes to the
same buffer. (eg: try the recipe again but exchange the role of
*Messages* and *Backtrace*, you will finish with a blank buffer for backtrace, that you can quit again to end up to the same point)
The second patch is a proposition to clarify a little the code.
