That's true, but it seems like an unnecessary complication. For instance, the mode line contains `minor-mode-alist', and has to loop through it to find the lighters to display. It could instead work off of the `minor-mode' list, which is order(s) of magnitude shorter for most people. (And whatever mechanism we add for global modes. Just adding a `global-minor-modes' variable is the obvious solution, but I was hoping somebody had a non-obvious alternative.) -- (domestic pets only, the antidote for overdose, milk.) bloggy blog: http://lars.ingebrigtsen.no
