 * * NO_DOTGIT_DIR - Normally a "/.git/" will be appended to the repo
 *        path for non-bare repos (if it is not already there), but

 * * MKDIR  - Make the repo_path (and workdir_path) as needed.  Init is
 *        always willing to create the ".git" directory even without this
 *        flag.  This flag tells init to create the trailing component of
 *        the repo and workdir paths as needed.
 * * MKPATH - Recursively make all components of the repo and workdir
 *        paths as necessary.
 * * EXTERNAL_TEMPLATE - libgit2 normally uses internal templates to
 *        initialize a new repo.  This flags enables external templates,
 *        looking the "template_path" from the options if set, or the
 *        `init.templatedir` global config if not, or falling back on
