Hi Robert,

Thanks for the review. The main issue with including uuencoded
testvectors in the document is that it would cause the RFC to be around
32000 pages long. That's why RFC6716 included the source code, but not
the test vectors. Back then, we were told that the meeting material was
the only place we could put the test vectors. I don't really like doing
that, but it still beats the other options I'm aware of (unless I missed
