Yeah, I'm fine with referring to git-config(1). I mostly want to avoid
that we have N locations that we need to update every time something
changes here, as those are bound to become stale.

Maybe a solution would be to only point out the config keys without
going into much detail what the respective values are? In that case we
woulds imply refer to git-config(1) and call it a day.
