Log message:
	In is_included_in merge some BE_LAZY=0 code into the BE_LAZY=1 case,
	and check if `x' is empty after minimization when BE_LAZY is 0.  In
	minimize() call simplify instead of update_generators and
	update_congruences, where possible.  Reduce all update_congruence
	calls to account for the fact the resulting grid always contains at
	least one point.
