Git: Stop specifying --global in git config
Git: Stop specifying --global in git config

When we're just reading config values, we don't have a good reason to
specify `--global` or `--local`. The command will, by default, read from
all possible configurations and prefer the most local one (i.e., the
repository, then the user config, and then the system config).

In addition to being overly restrictive, `--global` also prevents `git
config` from processing includes, which makes it harder to configure git
across multiple machines.
