I hit Send too early. If no one has modified the tag, --limit 1 would yield the same results as --stop-on-copy. But if someone *has* modified the tag (which we agree shouldn't happen, but depending on your setup, it could - that's a whole other matter), that modification will appear instead of the copy which created the tag. If you use --stop-on-copy, you can detect this condition and the oldest log will end up being the creation of the tag.
