Remove stale TODO regarding member rule combination for -if rule.
The scenario we worried is that some of combinations of member rules are
equivalent if we're trying all combintaions of all sizes: kind of
range(memberKeepRules.size()). But we already limit the size of elements
per combination as the size of member rules to satisfy, and thus such
case does not happen at all.
