What you already know, but probably badly explained ;-).

Eventually, the output of "git branch" should correspond to a format
string (so git branch would be almost an alias for "git for-each-ref
refs/heads/ --format '...'"). Internally, this would mean using
show_ref_array_item instead of print_ref_item. This is what you managed
to do for "git tag".

You already identified one difficulty with sha1 alignment in "git branch
-v". I'm pointing out another which is that displaying the "*" in front
of the current branch is currently not possible with a format string.
You would need an atom like %(displayAStarIfTheBranchIsTheCurrentOne)
(for which you'd need to find a short-and-sweet name ;-) ).
