Relative quasi-regular immersions

	Only the notions of H_1-regular and quasi-regular immersions
	behave well with respect to base change if one doesn't assume
	the ambient space is flat over the base. Of course if the
	ambient space is flat and of finite presentation over the base
	then everything behaves as it should and all 4 notions are
	equivalent.
