`git show-branch --upstream` is equivalent to `git show-branch
$(git for-each-ref refs/heads --format '%(refname:short)')
$(git for-each-ref refs/heads --format '%(upstream:short)')`
`git show-branch --upstream foo bar` is equivalent to `git show-branch
foo bar $(git for-each-ref refs/heads/foo refs/heads/bar
--format '%(upstream:short)')`
Combined with --topics, it shows commits that are NOT on any of
the upstream branches.

Note that in the --topics --upstream case, when there are different
upstreams branches involved, only the merge-base of all of them is
shown. I'm not sure if it's desirable to show more. The output as it
is works for my own use cases.
