gEDA-dev: Netlist contains U? on nets from the top-schema

[Christian Riggenbach]

Hi

I found a bug in processing hirarchies of schemas to a netlist.

I have a top-level schema and 10 sub-level schemas. When I generate a 
pcb-netlist from it, all top-level netlines contains additional to the right 
components a component/net "U?-?". The netlist and the schemas are aviable on 
http://trashbin.magahugu.net/AVR-Board.tar.bz2 (about 1MB)

Additional, the KSR_9- to KSR_15-nets are generated when there's nowhere a 
component to link to. I think this bug is not so important, because not so 
common to define in the schema-symbol and in the schema an 
off-sheet-connector and don't use it then.

my kind regards
