It would be really nice if, when a duplicate refdes was found, that the 
system would provide some notification and/or ask permission to link the 
symbols.  That would require a unique ID attribute be assigned to each 
symbol, then their could be a delimited list of 'linked' IDs as a second 
new attribute.  This would also provide a method to preserve 
autonumbering across split components/symbols.   ('No the op-amp in the

bottom-right. DFNSDK GM HG SHK gnetlist!!!')

Title:
  gnetlist doesn't detect duplicate refdes

Status in GPL Electronic Design Automation tools:
  Won't Fix

Bug description:
  gnetlist (I've used the PCB frontend) does not detect
  duplicate refdes.

  -------snip-----------
  werner@work:~/daten/elektronik> grep R11 output.net 
  unnamed_net23   R11-2 Q1-B 
  unnamed_net19   S2-1 R11-2 
  unnamed_net6    R11-1 R8-1 U1-18 
  Z0      R11-1 U1-2 
  -------snip-----------

  Question is, should gnetlist recognize and warn about
  duplicate refdes?
