Comment (by jmantysalo):
Nathann, thanks for noticing my error. Of course the function must be
`...is_subgraph(..., induced=True)`.
I think that `induced` means slightly different thing in graphs than in
posets. Or that poset just is a different way to see DAG than looking it
as a digraph.
Travis, you mean an `EXAMPLE` block with `has_isomorphic_subposet` shown
for reference?
