I repeated the same experiment, and got essentially the same number of
collisions (829 collisions on ~2 million randomly generated numerics,
with 273 duplicates). Since the modified hash still uses hash_any() and
really only differs when there are leading/trailing zeros, this is
consistent with what I'd expect.

Patch applied to HEAD.
