Hi Phillip,
it does not work for a fresh clone of an empty repository
git for-each-ref --format="%(upstream:short)" refs/heads/master
outputs nothing, while
git status -b --no-ahead-behind --porcelain=v2
outputs
# branch.oid (initial)
# branch.head master
# branch.upstream origin/master
I.e. it outputs a proper upstream branch.
Best regards
Ondra
