Thanks, Phillip and Rene.

It seems the shortname. Because "a.txt" is using same form, and
"no shortname" is meaning a "broken directory entry" in fat spec.

Yes. We would not need special case for devices.

I'll remove reserved names from vfat/msdos, because many OSes/commands
(even Windows) creates it.

Thanks.
