Hey, just calm down a bit and take a few long deep breaths! You've snipped my argument and left only the supporting discussion. I'm NOT arguing that anybody should have this "barely tolerable behaviour" thrust upon him; the user should be able to set his system up as he wishes. I'm merely saying that in a few years time the point will be moot. And that for Emacs 23, we will be able to set the default value of open-paren-...-start to nil, just as in Emacs 22 font-locking is enabled by default. Hopefully Emacs will always be such that wierdos who, for whatever reason, want to run with font-lock disabled, or on bare TTYs, or on early 1990s machines can do so comfortably. ;-) [ .... ] > -- > David Kastrup, Kriemhildstr. 15, 44793 Bochum -- Alan Mackenzie (Ittersbach, Germany)
