I support the general goal, we have quite some way to go there.

As to the method: "git branch" in list mode, "git tag" in list mode and
"git for-each-ref" all do similar things and are in turn not dissimilar
from "git log --no-walk" with appropriate formatting and rev options.

Rather than extending "git branch" any further[*], I suggest a bolder
strategy:

- unify/merge for-each-ref and pretty formats (and code) as far as possible
- leverage that for the list modes of branch and tag

That would allow everyone to get their favourite listing, just like for
logs. Otherwise it would be very difficult to agree on *the* proper
format for an extended branch or tag list.
