That's true. Hm... Should major modes remove `invisible' text properties (where the value isn't t)? No, that wouldn't be right, either. Uhm. OK, if `buffer-invisibility-spec' isn't t, `kill-all-local-variables' could remove the `invisible' text property from all text that has a non-t value? That sounds like it would potentially be expensive, but a non-nil invisibility spec is quite unusual (and switching major modes, in general, is unusual (well, switching from anything but fundamental-mode is unusual)). I dunno. Anybody have an opinion here? -- (domestic pets only, the antidote for overdose, milk.) bloggy blog: http://lars.ingebrigtsen.no
