This applies to the patches throughout the series, but during the
microproject reviews, Eric pointed out that we seem to start the
summary after area: on the subject with lowercase and omit the full
stop at the end, so I'll try to tweak the subjects while queueing to
read patches in the series.

Interesting.  So the test used to expect failure, but we couldn't
tell if that was due to giving a "Please update to this value" which
is malformed, or "I am giving 0{40} as the old value, telling you
that you have to make sure the ref does not exist" which does not
hold because we already have that ref?

That would mean that the test may not have been testing the right
thing.  A good change.
