No, that's not right...

So, when I look at my copies of the files, its as expected.

I put the test cases in the order 1, 3, 2 when pasting into the 
email—the labels are right, but that order was rather stupid on my part. 
But you must be looking at the right one, because you see the kernel 
option, so I'm confused.

I have no idea what the mailing list will do with this attachment, and I 
apologize in advance if you don't like binary attachments, but here they 
are as a .tgz. Should at least take care of this confusion.
