Yeah, surprising at first but then again it does feel sensible when
thinking about it: we ask git-config(1) to explitly list the
global/system-level configuration, and when it does not exist it does
feel sane to complain.

Whereas this is the other edge case: we do ask it to explicitly list the
system-level configuration, and it _does_ exist even though it's empty.
I wouldn't expect to get an error here, and I do prefer this behaviour
to NOSYSTEM, too.
