Wez, that patch allows for the possibility of a future 'goto' (which it 
calls 'jump'). It just doesn't implement it...

I think not many people use it because it's difficult to use.
Having real labels might change that.
Personally, I'd prefer real goto, as I've stated in the past.
Just for the record again, I'm +1 for goto, and +0.5 for labelled
breaks only if we've totally given up on goto.

--Wez.
