// REVIEW: This changed from a global config file to a
        // config directory
        // While I'm in favour of this change and generally like it.
        // i.e. it also fixes the question where the "identities" directory
        // is based on the "~/.pijulconfig" file
        // However in theory this is breaking.

    // REVIEW: Is there not a better way to get the repository root path
    // i.e. how about following steps:
    // 1. run something like Repository::find_repository_root project independent
    //    I guess for this to work properly the "repository" option should be moved
    //    from the common_opts to the Opts struct with "global = true" set
    // 2. load configuration

                //REVIEW: I guess we could inform the user here if there went
                // something wrong during the command "pijul remote default"

            //REVIEW: I don't get what the pager has to do with the coloring
            // Probably the pager stuff should also be refactored
