Title: Documentation for draw_networkx_edge_labels is wrong

The documentation for `draw_networkx_edge_labels` says that the pos label is optional, and the spring layout is used by default. However, I can't call the function with only the graph as the first argument. I get an error saying that it takes two arguments.
