There's no conversion, but there's no ``input failure'' either (in my
opinion).

As a matter of fact, I don't understand how can _any_ input failure
happen in scanning a string, except if the string's address is
invalid, like a NULL pointer.  (Perhaps we shopuld catch SIGSEGV
inside sscanf?)  Maybe it's a good idea to ask that om comp.std.c.

Maybe they have a definition of an ``input failure'' that is different
from what my intuition tells me?
