OK, this is not a gnuplot problem, but seems to be due to the following
changeset:

  changeset:   9729:3b7e644bb46d

  summary:     Treat markerfacecolor and markeredgecolor properties for lines 
and surfaces

The problem is that we are sometimes generating things like

  "with  linestyle 4"

instead of

  "with lines linestyle 4"

at this point

          style = do_linestyle_command (obj, obj.color, data_idx, mono, 
                                        plot_stream, errbars);

          withclause{data_idx} = sprintf ("with %s linestyle %d",
                                          style{1}, data_idx);

in scripts/plot/__go_draw_axes__.m (near line 525).  Here is a simple
example that should demonstrate the problem:

  figure (1, 'visible', 'off')
  plot ([1, 2], [3, 4], 'r+');
  print ("foo.eps", "-deps");

When evaluating these commands, I see

  octave:1>   figure (1, 'visible', 'off')
  octave:2>   plot ([1, 2], [3, 4], 'r+');
  octave:3>   print ("foo.eps", "-deps");

                           ^
             line 0: expecting 'lines', 'points', 'linespoints', 'dots',

          'yerrorlines', 'xyerrorlines', 'pm3d', 'labels', 'histograms',
           'image', 'rgbimage'

It looks like obj.linestyle is "none" in the do_linestyle_command
function in __go_draw_axes__.m and that results in setting style to
"".

I'm not sure what the proper fix is.
