Hi, Carsten,

I understand what you're saying. I've been looking at the functions
responsible for moving trees around and still can't get my head around
them. Not that this means much, as I'm just starting to dabble in some
elisp and don't have lots of experience with other languages either,
but I still see it would require a lot of work.

Let's see. If I manage to get a better hold of elisp, maybe I'll try
to make a patch. For now, those parenthesis still make my eyes
cross...

Thanks,
