	When toplevel's wid is -1 it means that it is a head node in
the link list and it does not serve any purpose other than a placeholder
(it doesn't have any gtk widgets associated with it).  I wouldn't mind if
we got rid of all old style link lists in libgeda/gschem at some point,
but for now, you should check for and ignore toplevel's with wid == -1.
