I don't remember what I intended, but it's a lot easier to regard
the test cases as incorrect than to regard the spec as incorrect,
so I favor that resolution of the problem.  I'll wait a decent
interval to see whether other problems come to light, and then
submit a pull request that fixes the test program.
