Like I say it's for review - it's much easier to look at a diff and
verify that it does exactly one thing than it is to verify that it does
a series of unrelated things, that all of them got covered, that there's
no unexpected additional changes and that all of them are complete.

You're doing three things here - you're changing the revision that's
printed, you're rewriting the text that's output for some reason and
you're changing the way the number of DAIs is stored and you only
mentioned two of those.  My first thought when I saw this change, just
looking at the shape of the diff rather than reading the text of the
message, was that it didn't belong and I needed to slow down and look in
more detail.  Had it been mentioned in the log I would have been
expecting to see some random text only updates, making this less of a
surprise.
