I didn't see Handa's message (there was a wierd burp in the emacs-devel mailing list, so perhaps it got nuked there...), but I did a grep and you're right -- a bunch of code uses ?\_ to mean ?_ . I can't imagine _why_ people did that, but they did, so I guess ?\_ is no good. Bleah. I really don't like the wierd double identity of ?\s, but I'm not sure what alternative there is... Perhaps kim's idea (?\SPC), but with a less ambiguous syntax, e.g., #\SPC or something. Does xemacs do anything about this issue? -Miles -- Fast, small, soon; pick any 2.
