Configuration to write to /etc/gitconfig. A list can also be
specified to keep the configuration in order. For example, setting
`config` to `[ { foo.x = 42; } { bar.y = 42; }]` will put the `foo`
section before the `bar` section unlike the default alphabetical
order, which can be helpful for sections such as `include` and
`includeIf`. See the CONFIGURATION FILE section of git-config(1) for
more information.
