Weird! I used Windows to rename test.txt and it renamed them all. Haven't
tried deleting yet, but it sure looks like a good way to hide files. I
wonder if it would be possible for 1!:0 to list those files like test.txt:a?
That would give full support. Otherwise, those files could be around and no
way to find them.
