I agree; I do not like the idea of this proposed 
enhancement of finish.  I think that if the source
looked like

	foo (bar ());

and I stepped into bar, then said "finish", and 
found myself in foo, I would find that confusing.
It would seem as if bar had been called from foo, 
which is not the case.
