Yes. Now it uses gnuplot 2-d plotting instead of 2-d projection of
2-d plotting it uses with the current version of contour.

That was the said difference between plot layouts in true 
2-d plotting and 2-d view of splot. The latter one apparently 
makes more margins for labels and Henry compensated for it
by adding  "gset origin 0.30,-0.07". When used with your new
contour that command pushes plot too low and that clips off
the xlabel. Plot looks fine without it. Sorry for false alarm here.

Currently, with your new contour, if you type 
contour(x,y,z)
(no ";" at the end) it prints out on the terminal
the "s" values which I did not ask for.
The desired behavior is:

contour(x,y,z)          --> plots the figure no output on the terminal window
s=contour(x,y,z)        --> plots the figure, returns s, prints s on the 
terminal
s=contour(x,y,z);       --> plots the figure, returns s, does not print 
anything on
                                the terminal

(compare that with "hist" for example)
