(I thought I'd sent this email last week, but I don't see it in the
archives or my sent items)

I've pushed a fix similar to your v1 patch for this. I used
foreach_current_index rather than what you did in your v1. That seems
less prone to get broken again in the future if someone were to add
additional logic within the loop body.

I didn't see any need to do any more than that, so I didn't consider
anything your v2 patch did.

Thanks for the patch.
