I'm not sure -- you're the one who said it was? But it does to a lot of work, dropping into the start/stop machinery and doing computations. This new property is purely on a char by char basis, so it doesn't have to do any of that stuff. > I'm not sure I understand the "recursive" part: if some string has a > certain value of some text property, then every character of that > string has that same value of that property, and thus you cannot have > some of those characters have the same property with a different > value. So how can the "recursive" part work in practice? You'd have to maintain a stack in the `min-width' machinery to handle "overlapping" (or rather, nesting) min-width display properties. I'd rather not. -- (domestic pets only, the antidote for overdose, milk.) bloggy blog: http://lars.ingebrigtsen.no
