Fair enough. I suspect a number of people scan the code, but few feel
invested enough to formally Ack it. Also, providing a full review of
such a series can take quite a bit of time. Against that, I think it
is better to get code in and tested than have it sit around until just
before the next release.

Thanks for looking at it. Some of it is just the code moving around,
but I will take a look at why hash_command grows so much, and why the
overall size has grown. Clearly I didn't do enough here when I checked
the series. One change was trying to unify the verify feature, so
perhaps something has gone wrong there.

We need more reviewers I think.
