-----------------------------+----------------------------------
`partial`-argument on `maximal_chains()` of finite posets is broken. The
error is at `posets.py`.
{{{
P = Posets.BooleanLattice(2)
P.maximal_chains(partial=[1, 2])
}}}
outputs `[[1, 2, 3]]` which is not a chain at all. Best correction is to
remove the option.
