Yes, I'm aware of this.  The point I was trying to make is that the OP,
and also the follow-up posters, were subjecting the entire community to
the unnecessary work of looking up these hash codes.  This makes me
annoyed.  I was gently suggesting that people not repeat this practise.

Anyhow, thanks for posting the information.  There is nothing in any of
these commits I know anything about.
