'[<branchname>]@\{upstream\}', e.g. 'master@\{upstream\}', '@\{u\}'::
The suffix '@\{upstream\}' to a branchname (short form '<branchname>@\{u\}')
refers to the branch that the branch specified by branchname is set to build on
top of (configured with `branch.<name>.remote` and
`branch.<name>.merge`). A missing branchname defaults to the
current one. These suffixes are also accepted when spelled in uppercase, and
they mean the same thing no matter the case.
A branch B may be set up to build on top of a branch X (configured with
`branch.<name>.merge`) at a remote R (configured with
`branch.<name>.remote`). B@{u} refers to the remote-tracking branch for
the branch X taken from remote R, typically found at `refs/remotes/R/X`.
'[<branchname>]@\{push\}', e.g. 'master@\{push\}', '@\{push\}'::
The suffix '@\{push}' reports the branch "where we would push to" if
`git push` were run while `branchname` was checked out (or the current
`HEAD` if no branchname is specified). Since our push destination is
in a remote repository, of course, we report the local tracking branch
that corresponds to that branch (i.e., something in `refs/remotes/`).
`HEAD` if no branchname is specified). Like for '@\{upstream\}', we report
the remote-tracking branch that corresponds to that branch at the remote.
