I don't see a reason why this shouldn't exist, and the patch that you
wrote below looks pretty good to me.

To refresh my memory on if you had missed any spots, I followed
0df621172d (pretty: provide short date format, 2019-11-19) as an
example. You did a fine job here, and I don't think this patch is
missing anything.

Just to make sure I understand what you wrote: you're saying that the
pretty formats "%ah" and "%ch" that you propose here could be achieved
with --date=human and --pretty="%ad". Makes sense, but I agree that your
point about --date=iso8601 having a built-in pretty atom makes the case
for having "%ah" and "%ch".

There's no sorting here, so this place (at the bottom of the author-date
placeholders) seems just as good as any.

Likewise. The rest all looks good to me, too.
