	Attached are two files: pins.sch and pins.prj. After running
"gsch2pcb pins.prj", opening the pins.pcb file in pcb, loading the netlist
and [o]ptimizing rats' nests there is only one rat line between R1 and R2.

	I was, however, wrong about pcb silently discarding the other rat lines
- if I explicitly open the message window, there are warnings. However,
the message window is not opened by default, and there is no other notification
that something has gone wrong, which I think is not good from the usability
point of view.

	BTW, when I try to do a DRC check, pcb crashes. A similar crash
together with details like backtrace and so on is described here:
