Details:

octave:1> [x,y] = meshgrid(-2:.2:2);
octave:2> t = linspace(-2,2,10);
octave:3> z = (1+x.*y).*(x+y);
octave:4> plot3(t,t,t)
octave:5> hold on
octave:6> surf(x,y,z, "FaceColor", [.3 .5 .3], "EdgeColor", [0 0 0])
octave:7> version 
ans = 3.2.4
gnuplot -V
gnuplot 4.4 patchlevel 0

When the result was returned the FaceColor property had not been set to a
single color, it was still the default color map. Also the line could not be
seen superimposed on the side of the surface it was graphed with. It was only
visible when the plot was oriented so that the line was in front of only
whitespace. When the surface was plotted first, and then the line, the line
could be seen in front of the surface as expected, but it could also be seen
behind the surface where I would expect it to be hidden.
