We can even do that "ref target || object name" thing with

--format='%(refname) %(if)%(symref)%(then)%(symref)%(else)%(objectname)'

if we wanted to. But if we have both available, I think the output that adds the symref target, if available, after the object name, is better than the output that switches between the two.

Yeah, I know we discussed the usefulness of tag-of-tag-of-something, but this is a similar one.

Indeed.  Thanks for an interesting thought.
