Hi Kito,

I’ve sent my assignments and my school’s disclaimer to ass...@gnu.org 
<mailto:ass...@gnu.org> ([gnu.org #1673033] Xing GUO), but I haven’t got 
response so far. Not sure if this patch can be accepted as  a small bugfix 
patch. If not, I’m happy to wait until FSF prove it.

Best Regards,
Xing
