Yes. I got confused at another point. No, wait! Now I see what
happened to me: the vim, where I'm editing this shows things in
the wrong order! It's not doing RTL at all. So while I thought
I was looking at what happens in Emacs, and not paying attention
at what my mailer shows -- somehow I was picking it up, subliminally.

So sorry for the noise -- and thanks for teaching me something.
And for your very special humour :)
