not really, and Stravos has convinced me that it is a terrible idea. The
two options above are good enough.

I was not proposing a new syntax. $plot_options, as defined in plot.lisp,
already has things such as 

                        ((mlist) $grid 30 30)
                        ((mlist) $view_direction 1 1 1)
                        ((mlist) $colour_z nil)
                        ((mlist) $transform_xy nil)

certain options as $gnuplot_preamble are clearly gnuplot specific. But I do
not see why gnuplot_curve_styles could not be simply curve_styles, with
a syntax similar to colour_z or grid.
