If the pins are overlapping in the sym, the semantics must (?) be that 
they have a cu path internally, or ?

If you have something that looks like one pin, shouldn't that iimply 
that regardless of which "sub-pin" you use, you get the same connection.

If you have pinnumber=2,7,8 and connects a NC sym directly to that, do 
you want the NC sym be implicitly triplicated ?
 What if you move the NC sym a little so there is a little short net,
and then what if the net is connected to something else ?

I think only meaningful semantic is if it looks like "one" pin, it 
should behave as if all "sub-pins" share the same cu-path internally.

///

Now for the case of ic's with lot of NC pins, maybe just not drawing
thoose pins in the sym is the solution. What do you think ?
