One tiny thing is all, and doesn't actually matter.

I guess next step would be doing the same the other way round (for --force-new) and have it check it's new. Then I wonder if we can actually combine the renewal/new handling so that it's not needed at all and we can only have one loop through that finds a 'relevant' report (regardless if DD is new or renew) and does something, but could that cause a problem somehow. You'd hope not, because there shouldn't be the 'other' thing in either case...
