It's conceptually done like that in latest build (I took a bit of  
freedom wrt the counter, since I already push/pop the markers on a  
stack ;) ).

Most languages only fold on { and }, or use a generic 'end' keyword  
to end different start blocks, so not much would be gained from this  
-- HTML comes to mind as one where there are different paired  
elements, but one could still have nested divs with same indent etc.
