Looks like by default a value is always set in a local
config, which might be dangerous for remote.* or gc.*
parameters, for example. I think that even if reading is
done uniformly setting could depend on the actual variable
being set if no location specified.

Shouldn't "+ use_repo_config" do here to the left part of
comparison?
