Aha! I completely missed this but it is indeed weird. Something
similar happened to me when I was sketching some patches for tag
verification in a downstream project...

Yes, I think chaining this if here is cleaner/less error prone.

Let me make a re-roll with these changes included and a test suite for
both t7030 or t7004.
Thanks!
