  Modified files:
    .                    capture.c 
  Log:
  If "pcap_compile()" fails to compile an empty filter string (because,
  for example, the libpcap code generator doesn't support the link-layer
  type for the capture), "dfilter_compile()" will succeed but return a
  null rfcode pointer.
  
  In that case, instead of telling people that it looks like a valid
  display filter (which it does, but it also looks like a complete list of
  all the Basque words likely to be known by Hammurabi :-)), and then
  crashing when we try to "free" that non-existent dfilter code, we just
  report it as a "sorry, couldn't compile that capture filter.
