I think this is a right patch but I'm not 100% sure because I don't understand redisplay. The problem is, Fsplit_window incorrectly invalidates face cache when splitted window has no parents. This doesn't make sense because Fsplit_window only adds new modeline between windows and scrolls window to make point visible. They don't change any faces. Function and variable names are very cryptic in these functions. I'll probably refactor it when I have some more time. 2000-12-04 Yoshiki Hayashi <yoshiki(a)xemacs.org&gt; * window.c (Fsplit_window): Don't invalidate face cache.
