I can see why you ask that. empty_hash_code is chosen by the user to
indicate an empty table slot and the function is embedded in a generic
package having empty_hash_code as a constant parameter of the instantiation.
So it might not be zero, and I don't see much reason to start h off at
anything other than 0.
