This solves the problem quite naturally, because any tree that hasn't been
parsed - or even if it *has* been parsed, but just hasn't gone through
the compare function - will then always be seen as "different" and thus
interesting.
This fairly straight-forward patch seems to work. It *replaces* the
pervious "patch 4/2", and yes, Junio, I think you were very right to
complain about that one.
How does this one feel?
I think this is very natural and I like it.
I did not complain but just said I was puzzled, but after
thinking about this a bit I probably should have ;-).
