In an earlier message, Nathan Kopp said that NO_GLOBAL_LIGHTS_SET_FLAG in
objects.h is unused and should be removed. However, it is used in one piece
of code, around line 2858 of parse.cpp (at the end of Parse_Light_Group):

Set_CSG_Children_Flag((OBJECT *)Object, Test_Flag((OBJECT *)Object,
NO_GLOBAL_LIGHTS_FLAG),
NO_GLOBAL_LIGHTS_FLAG, NO_GLOBAL_LIGHTS_SET_FLAG);

There is no other code that uses NO_GLOBAL_LIGHTS_SET_FLAG, so I suspect
this is a bug.
