I though Ben still reads xemacs-beta?

Ben, can you comment on this? Is this how things are supposed to
work?
Gunnar, you might be interested in the latest patch by Yoshiki, which
seems to make exactly the change necessary for the above to work
right. (But then again, it might not, with XEmacs it's hard to tell.)
I doubt that this helps. I think the problem at a far lower level. In
Simon's case we never get anywhere near the lisp command loop. The
problem is that the X event that corresponds to C-g is not in the X
queue (yet) and thus the XCheckIfEvent() in x_check_for_quit_char()
doesn't find it.
