Comment:

 This LGTM except for this change:
 {{{#!diff
 -            sage: G = DiGraph(M,sparse=True); G
 +            sage: G = DiGraph(M,sparse=True,weighted=True); G
 }}}
 I'm worried that this change of behavior of how you handle weighted graphs
 could break other people's code. Unfortunately I can't comment on the
 correctness of either behavior, but it might have been a "feature" that
 others were using.
