git for-each-ref --format="%(upstream)" $(git symbolic-ref HEAD)

I can't come up with a better way of expanding @{u} without resolving
the resulting refname to a SHA1. You could do

git name-rev @{u}

or similar with "describe", but that's really backwards - it first
expands @{u} to a refname, then to a SHA1, and then tries to describe
that SHA1 by a refname...

BTW: Please don't change "--set-upstream" light-heartedly and isolated
from other stuff. We need more consistency wrt. subcommands vs. options
vs. options taking parameters. So an incompatible change should be part
of a bigger picture. This requires some research about our current
usage, pitfalls, and the best way forward (breaking as little as
possible and achieving as much as possible).
