I think it was just an honest mistake.  The error message is supposed
to apply to use of the image_map pattern in a normal block.  In older
code, normal and pigment were the only things that used patterns, so 
it would have made sense to force image_maps to be inside pigment blocks.
Odd, though, that the other two cases of things that could only be used
in pigment blocks (color and color_map) were fixed and image_map was 
not.
