I did some experimentation using the test case Jakub presented
to start with, and verified that that loop does respond promptly
to control-C even in HEAD. So there are CFI(s) in the loop as
I thought, and we don't need another.
What we do need is some more work on nearby comments. I'll
see about that and push it.
