Hello everybody !
A poset with embedded linear extension can never be equal to a "simple
poset", and users are bound to wonder someday why two apparently equal
posets are not detected as such.
With this branch, this:
{{{
sage: Poset(digraphs.Path(5),linear_extension=True)
Finite poset containing 5 elements
}}}
becomes
{{{
sage: Poset(digraphs.Path(5),linear_extension=True)
Finite poset containing 5 elements with embedded linear extension
}}}
So that it is clearer that the Poset is 'not only a poset'.
