* kern/misc.c (grub_strncat): Fix off-by-one error.
        Reported by Zhang Huan <zhanghuan@nrchpc.ac.cn>

        * kern/env.c (grub_env_context_close): Clear current context, not
        previous one.
        Patch from Zhang Huan <zhanghuan@nrchpc.ac.cn>

        * kern/misc.c (grub_strcat): Minor speed optimization (same code size).
