    epan                 packet.c 
  Log:
  In all the routines that set "pinfo->current_proto" before calling a
  dissector, save the current value of "pinfo->current_proto" and restore
  it before returning; when you return, you're back in the dissector that
  called the routine to call a dissector, so the current protocol is the
  one for that dissector.  This may be important if a dissector calls a
  subdissector and, after it returns, processes stuff in the packet after
  the stuff dissected by the subdissectror.
  
  This means it's safe for "dissector_try_heuristic()" to set it before
  calling a heuristic dissector, as it'll put back the previous value when
  it returns.
