The point is the confusion between documents and views here.
Sometimes, a change in the initial environment should rather
be interpreted as a change in the view (no change in the document)
and sometimes not. What we really need is a clean extra level for views,
but that is quite tricky. I plan to study this carefully when
elaborating the new document editing model.
