Hmm.. I thought it wouldn't affect gnetlist, since promotion isn't
enabled with reading in saved schematic files.

BTW.. I wanted (still do) to move the attribute promotion code out of
o_complex_add(), so all such functions can become OBJECT *o_???_new(),
and not require returning GLists of objects *when finish the patches to
turn the main object list into a GList. At the moment, attribute
promotion is the only reason a o_???_add() function needs to return
multiple objects at once, meaning more special cases in the
implementation.
