You could use half a neuron and check the return value of fg_world(),
perhaps. :)

/def quit=\
  /if (fg_world() !~ "") \
    /dc %;\
  /else \
    /@quit %;\
  /endif

But this won't match what you said above -- it will not disconnect a socket
if there is still one left and you just happen to be backgrounded right
now.  You could check %? after running /listsockets -s for that.
