Subject: [PATCH 2/6] config: add string mapping for enum config_scope

From: Emily Shaffer <[email-masked]>
Date: Mon, 9 Dec 2019 18:33:31 -0800

If a user is interacting with their config files primarily by the 'git
config' command, using the location flags (--global, --system, etc) then
they may be more interested to see the scope of the config file they are
editing, rather than the filepath.
