Unintuitive overlap output.

[pyrrhicPachyderm]

When performing overlap -1 or 1, a node that has no incoming or outgoing links respectively (and so 0 of out 0 of its neighbours overlap) is treated as having an overlap of 1. This seems a little unintuitive. Is there a reason behind it?

Can you point me to the exact place in the code where this is happening?
