ibuffer-auto-mode

[Colin Baxter]

Hello,

With emacs-28, I find I now have to set explicitly ibuffer-auto-mode to
nil in my ~/.emacs in order for the menu popup <f10> to work in
ibuffer. Otherwise I get a "void-variable ibuffer-auto-mode" error. This
isn't needed for emacs-27. It isn't needed for "emacs-28 -Q" either; so
presumably something about my setup triggers the void variable error,
but I can't find anything that's obvious. I'd be grateful for
suggestions as to where to look.

I know the def for the ibuffer-auto-mode has been changed, but even if I
revert back to "nil nil nil" from ":lighter nil", the void-variable
error is still triggered without the (setq ibuffer-auto-mode nil)
setting.

Best wishes,

Colin Baxter.
