I thought about that, but I'm not sure that it proves much more than just using
zero. The test doesn't really do much of interest with this value, and it
doesn't seem worth complicating the test. The idea originally was that perl's
"q" pack code would make reading/writing a number such as 12345678 easy, but
since it's not easy, this is easy.
