13 ** It is actually checking if s1 is a PREFIX of s2.
14 ** All calls to this function need to be checked to see
15 ** if that needs to be changed. Prefix checking is cheaper, so
16 ** should be kept if it's sufficient.
20 ** Check if s1 is a substring of s2.
21 ** If yes, then return 1, else return 0.
