This is the behavior consistent with how all of the other objects are treated 
by .kst.

I think it is in fact easy to be backwards compatible.  

In loading make a PlotList of all plots which have been loaded.

At the end of loading put 

if (no windows have been defined) {
  make a default window
  attach all plots to it
}

This approach is OK, but inconsistent with the way everything else is done.
