sagemathgh-40836: Fix BipartiteGraph.vertex_cover(value_only=True) for disconnected graphs For a graph G, `len(G.vertex_cover())` should always equal `G.vertex_cover(value_only=True)`, but this was not the case when G is a disconnected `BipartiteGraph`. The fix is shockingly simple. URL: sagemath#40836 Reported by: Lennard Hofmann Reviewer(s): David Coudert
