To my surprise I can not reproduce this now. I did several tests before 
with emacs -Q and it work the way I described all the times. Richard 
can't see it, Jason don't see the problem, I could see it but not now. 
It is beginning to look like a possibly intermittent hardware memory 
problem to me. But I am not sure yet, those are hard to track down. So - 
just drop it for now at least. I will come back if I come to another 
conclusion than the one above.
