If not, then it is probably safe!
At first I thought something similar, but that's not really a valid way to view the problem. If something else runs a hook that would normally execute after the one you are removing there is a potential for other hooks not to run on that command. Something like that would not likely manifest itself in a catastrophic way but could cause unusual behaviors that a conscientious coder would want to avoid. This line appears in remove-hook. (setq hook-value (delete function (copy-sequence hook-value))) It makes me think that a change to the hook's value will not be visible to the present execution of the run-hooks command. So I'd say it appears to be perfectly safe. _______________________________________________ Help-gnu-emacs mailing list Help-gnu-emacs@gnu.org http://lists.gnu.org/mailman/listinfo/help-gnu-emacs
