Now that all values that are collected into "sum" are unsigned long,
make the sum itself unsigned int so that it overflows consistently
with individual components and thus retains the monotonicity.
Since seq_put_decimal_ull() is a function, we don't have to explicitly
cast sum into unsigned long long. Integer promotion will take care of
that (and the compiler will issue warnings if the types don't agree).
