Why %(upstream:track)? ... I'm intrigued! 😀

[pvdb]

It's not wrong, but I was just wondering about the purpose of this line:

%(color:bold yellow)%(upstream:track)%(color:reset)

The %(upstream:track) directive is only relevant if you have two local branches, one of which is the upstream for the other one... put differently: it has no relevance for remote-tracking branches.

Like I said: nothing wrong with it, but I'm intrigued by the workflow where you have a local branch with an upstream local... ie. what kind of git workflow would give rise to this use-case?
