Hi Lute,
OK, I see now what the problem is, and I will switch to
define-derived-mode, and to run-mode-hooks (for org-agenda-mode).
This will indeed create a problem if someone uses outline-mode-hook to
modify one of the three outline menus (Headings, Show, Hide). We will
just have to see if anyone gets biten by this. I will implement the
change tomorrow - need to do some testing first.

LK> In Emacs, global-font-lock-mode (and any other global minor mode
LK> defined with define-global-minor-mode) adds one function to
LK> change-major-mode-hook and a second function to
LK> after-change-major-mode-hook to enable Font Lock mode. The first
LK> functions adds the current buffer to a list variable. The second
LK> function enables Font Lock mode for all buffers in that list and
LK> clears the list.
LK> change-major-mode-hook is run by kill-all-local-variables and
LK> after-change-major-mode-hook is run by run-mode-hooks. So normally, a
LK> major mode calls the first function once as the first thing it does
LK> and the second function once as the last thing it does. However,
LK> org-mode calls the second function halfway, before it sets up its own
LK> Font-Lock stuff. As a result Font Lock doesn't work properly for
LK> org-mode.
LK> Lute.
LK> PS. Putting the second function on after-change-major-mode-hook is a
LK> recent change, it used to be on find-file-hook.
