RFC 4226 <https://www.rfc-editor.org/rfc/rfc4226>, "HOTP: An
HMAC-Based One-Time Password Algorithm", December 2005
Another problem with the same document.
Recommend: Accept.
The reference implementations cited match this described behavior and
specifying the last byte of the HMAC makes more sense than always the
20th byte (correct for HMACSHA1 only).
