Comment:
At least
{{{
g1 = DiGraph({13:[14]})
g2 = DiGraph({13r:[14r]})
g1.is_subgraph(g2), g2.is_subgraph(g1)
}}}
outputs `(True, True)`. Is there examples of `sub*` function with
different behaviour? If not, then also `is_subposet()` should be like
`is_subgraph()`. CC to ncohen for this question.
