This is an interesting situation which is the inverse of the bidi 
problem.  In the bidi case there is a single point in the DOM which 
corresponds to two different user-perceived selection positions.  In 
this case, a single user-perceived selection position corresponds to 
multiple (could be more than 2) points in the DOM....

As an actual user of editors, by the way, the #1 thing that pisses me 
off about wysiwyg editors is precisely having situations like the one 
above and wanting to be able to make the text be "<b>foo</b>orbar" in 
some cases but "<b>foopy</b>bar" in others.  Wysisyg editors tend to be 
terrible at this sort of thing.  Is that something that's inevitable, or 
can we do better here?
