templatekw: clarify the result of {latesttag} when no tag exists My initial expectation was that the list would be empty, and therefore detectable with {if()}. The map for {latesttag()} is populated with real values in this case (except {tag}), so it probably doesn't make any sense to change this to an empty list.
