Comment (by dcoudert):
Well, I'm not sure which is the best behavior but I don't like the idea of
deleting an edge. So it could be better to set the flag to True when a
multiedge is created.
Nathann is right when he said that the method cannot answer all expected
behaviors. It will be different for flow problems than for orientation
problems.
