bug#7218: 24.0.50; Weird window resizing with ibuffer-auto-mode

[Tassilo Horn]

After invoking ibuffer with ibuffer-auto-mode enabled, all windows I
switch to using `C-x o' are shrunken to fit their contents.  Switching
windows again restores the original size.  That's pretty annoying.

Here's a recipe:

1) emacs -Q
2) In *scratch*, evaluate these settings:

--8<---------------cut here---------------start------------->8---
(defun th-ibuffer-mode-init ()
  (ibuffer-auto-mode 1))

(add-hook 'ibuffer-mode-hook
	  'th-ibuffer-mode-init)

(global-set-key (kbd "C-x C-b")
		(lambda ()
		  (interactive)
		  (ibuffer t nil nil nil 'onewindow)))
--8<---------------cut here---------------end--------------->8---

3) Press C-x C-b
4) The *IBuffer* buffer window shows *scratch* and *Messages* and is
   resized to fit its contents.
5) Press C-x o multiple times, and see how windows start shrinking and
   growing.

As long as the *IBuffer* buffer is alive, I get that strange window
resizing also when it's not visible and switching between windows
showing for example *scratch* and *Messages*.  As soon as I kill the
*IBuffer* buffer, it works again.

bug#7218: 24.0.50; Weird window resizing with ibuffer-auto-mode

It happens because `ibuffer-shrink-to-fit' shrinks the selected window
regardless of the buffer it displays.  I suppose doing something like

(defun ibuffer-shrink-to-fit (&optional owin)
   ;; Make sure that redisplay is performed, otherwise there can be a
   ;; bad interaction with code in the window-scroll-functions hook
   (redisplay t)
   (when (with-current-buffer (window-buffer)
	  ibuffer-auto-mode)
     (fit-window-to-buffer nil (when owin (/ (frame-height)
					    (length (window-list (selected-frame))))))))

would cure it.  But I'd rather not comment on calling a function like
`ibuffer-shrink-to-fit' in `post-command-hook' ;-)

It did indeed, so I've now pushed a fix similar to this to Emacs 28.
