Re: [PATCH v3/GSoC 2/5] path.c: implement xdg_runtime_dir()

For example:

    const char *enter_repo(const char *path, int strict)
    {
        static struct strbuf validated_path = STRBUF_INIT;
        static struct strbuf used_path = STRBUF_INIT;

        if (!path)
            return NULL; // no need to release, right?
        ...
    }

Correct.
