[PATCHv2 1/2] completion: add __git_config_get_set_variables() to get config variables

From: Stephen Boyd <bebarino@gmail.com>

Message-ID: <1241832213-23070-2-git-send-email-bebarino@gmail.com>
In-Reply-To: <1241832213-23070-1-git-send-email-bebarino@gmail.com>

This function 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.
