Why make it so complicated?

The fix I'd like to see is that if a numeric input is outside the
range of the expected type, it's treated like a matching failure,
though perhaps with some differences regarding how much of the
input is consumed.

For example, currently this:

    int n1, n2;
    sscanf("123 999999999999999999", "%d %d", &n1, &n2);

has undefined behavior.  I suggest that it should return 1, store
123 in n1, and not modify n2, just as it would if the input string
were "123 xyz".

The strto*() functions already have well defined behavior in the
presence of overflowing (or ill-formed) input.  I can't think of any
reason not to require *scanf() to behave equally sensibly, or to permit
different implementations to behave differently.

The implementation-defined abnormal program termination that you suggest
is only barely better than undefined behavior; it still would makes it
impossible for an application to handle bad input gracefully.

With the implementation I'm currently using (gcc with glibc), sscanf()
returns 2 and n2 is set to -1.  It doesn't blow up, but the incorrect
input is not detectable.
