Bug in order_ideal_complement_generators: 'down'

Description (last modified by chapoton) (diff)
The down option is broken in order_ideal_complement_generators due to a glitch:
sage: P = Poset( ( [1,2,3], [ [1,3], [2,3] ] ) ) sage: sage: P.order_ideal_complement_generators([1,2], direction='up') set() sage: P.order_ideal_complement_generators([1,2], direction='down') set()
The result should be  in the later case.
