Weird. Having done the above `add-to-list' in Emacs (with `C-x C-e'), I got a
different exported file than yours. But really different:

--8<---------------cut here---------------start------------->8---

There is no text, in fact...
Don't understand why...

I think as well we can live with such minor troubles for the moment. And still
take advantage of Org...

Though, I have a bigger problem getting to there.
