Notes

I didn't add additional tests as it might not be justified, but let me know otherwise.

Hi @leostewart thanks for the contribution - sorry we missed it until now. Could you add a unit test verifying that a 0 is printed to make sure this won't break again in the future?

Hi @WillieRuemmele, I've added a few unit tests for the mentioned scenarios. As this is a bit of an edge case, I wasn't sure how best to incorporate them into the existing tests, so feel free to make suggestions/changes.
