No problem. :-)
OK, I attached a draft where you can see what I had in mind.
(_moved_, not _copied_, as you said, "you don't want it duplicate". It is
not duplicate now. :-)).

P.S. Actually it would be better to have the SGML (or sorta) source handy
here, because editing the HTML reveals that it's generated by some
conversion tool (sgml to html or similar). Besides, I don't think the
maintainers like too see me hack around here like this, but what the
heck...:)
