Dag-Erling Smørgrav 9317242469 diff: Fix integer overflow. ... The legacy Stone algorithm uses `int` to represent line numbers, array indices, and array lengths. If given inputs approaching `INT_MAX` lines, it would overflow and attempt to allocate ridiculously large amounts of memory. To avoid this without penalizing non-pathological inputs, switch a few variables to `size_t` and add checks while and immediately after reading both inputs.
