280: No movement rotations exist in file

[tngreene]

A user sent me this snippet of an OBJ:

                        ANIM_begin
			# static translation
			ANIM_trans	-0.43759999	-0.26363999	5.39834023	-0.43759999	-0.26363999	5.39834023
			# rotation keyframes
			ANIM_rotate_begin	0	1	0	test
			ANIM_rotate_key	0	104.88794342
			ANIM_rotate_key	1	104.88794342
			ANIM_rotate_end
			ANIM_rotate_begin	0	0	-1	test
			ANIM_rotate_key	0	12.63257318
			ANIM_rotate_key	1	12.63257318
			ANIM_rotate_end
			ANIM_rotate_begin	1	0	0	test
			ANIM_rotate_key	0	3.09511794
			ANIM_rotate_key	1	-78.34510431
			ANIM_rotate_end
			# EMPTY: DoorAnim weight: 0
				# 4 Mesh: Comp
				# MESH: Comp	weight: 4
				# MATERIAL: E1
				ATTR_shiny_rat	0.38
				TRIS	702 309
			ANIM_end

Why did these do nothing rotations get included? And why after he deleted the Y and Z rotation channels?

Is this a one off or a bug? It may not be a big performance killer but certainly isn't our goal of a minimal file.
