I would enjoy this change! Gnuplot interactive mousing (e.g. zooming by 
mouse) is limited to the current window only (for which "replot" works).

For example, you need to popen() several gnuplots to work simultaneously on 
a map and its line cross-section. That way you bypass the octave built-in 
gnuplot plotting completely and define all commands through "in userspace".

The proposed built-in solution with
>    static oprocstream *plot_stream = 0;
>    std::map<int,oprocstream *> plot_stream_map;
>    static oprocstream *current_plot_stream = 0;
would be much more elegant and consistent.
