This makes it easier for users to get and unset their configuration
variables without having to open documentation or dig through their
configuration file.
__git_config_get_set_variables() retrieves the set configuration
variables from the appropriate configuration file. For example, if
the user has previously specified --global only the global variables
are returned. The same applies for --system, and --file. If no
location has been specified, all set variables are returned.
