    While grepping for AllEvents I found this in Intrinsic.h:

And if you'd grepped around the documentation you might have
deduced that Xt defines XtAllEvents for use in precisely the
situation where an invalid value is required.

Moral: making assumptions based on C code in header files is
dangerous.

Corollary: header files should have more comments.
(not fixed in R4, sorry ;-)
