Trying to do (setq display-buffer-fallback-action nil) and `M-x compile RET' goes to re-arrange the wrong window (that displays "*scratch*" in `emacs -Q') because the nil WINDOW arg of `set-window-start' defaults to the selected window, so yes, a nil value is not a good thing to return from display-buffer. > Maybe a way around that is to use a special window that's never > displayed. But that might introduce more trouble than it's trying > to solve. Trying to use an internal window: (add-to-list 'display-buffer-alist '("\\*compilation\\*" display-buffer-ignore (nil))) (defun display-buffer-ignore (&rest _ignore) (frame-root-window)) fails with `(wrong-type-argument window-live-p #)', so this is not possible to do without changes to the window framework to add a new window type for live hidden windows.
