Some snprintf() implementations may indeed do that, but not all.. For
example, _snprintf() in Visual Studio does not (or at least did not in
some versions) do that. There is even a following note on this in
documentation: "This function does not guarantee NULL termination, so
ensure it is followed by sz[ ARRAYSIZE(sz) - 1] = 0."
