Ah, yeah: (defvar whitespace-point (point) "Used to save locally current point value. Used by function `whitespace-trailing-regexp' (which see).") So that's basically the same problem I'm having here, and it's solved by machinery that keeps that variable updated in whitespace buffers, probably because font-lock doesn't provide that information? >> By the way, have I whined about how difficult debugging font-lock stuff >> is?
