Wouldn't it be nice to have a "(run-hooks 'kill-emacs-hooks)" upon
exit?
It is not in the documentation, but the following appears to work
fine:
(defvar kill-emacs-hooks nil
"Hook functions to be executed upon kill-emacs.")
(setq kill-emacs-hook '(lambda nil (run-hooks 'kill-emacs-hooks)))
I cannot be sure someone is using (or going to use) kill-emacs-hook
for other purposes, though.

There are a number of hooks defined in the C code that have this problem. Their semantics are those of: (funcall <C-definied-hook>) as opposed to: (run-hooks <Elisp-defined-hook>) run-hooks looks at its argument(s), an &rest-list. It eventually runs funcall on each list element that is a lambda or isn't a list, and mapcar's funcall over the lists. I think this functionality was added early on, but after the C-coded hooks were already in place; the latter skipped the elisp iteration on the list because of history. Up with symettry. Another vote for generalizing the C side of things. The only conceivable downside I can see is that the auto-fill hook (the thing that fills your long lines when you type a space) may slow down noticeably, but I tend to doubt it. Could always put run-hooks into C (it's in subr.el now). -- /jr, nee John Robinson What a waste it is to lose one's mind--or not jr@bbn.com or bbn!jr to have a mind. How true that is. -Dan Quayle
