Fix wordcmp return value when the words have differing lengths

Otherwise, the result of strncmp gets converted size_t, since size_t
has greater rank than int.

Since wordcmp is only ever used as a boolean condition, this poses
no real issue, but presumably, it is meant to behave like the other
*cmp function and return a value less than, equal to, or greater
than 0 depending on the result of the comparison.
