Well looking at the change log of why this change was made, the reason
is given as

2007-12-17  David Bateman  <dbateman at free.fr>

        * plot/__go_draw_axes__.m: Use "set pm3d explicit" so that
        contours can overlay pcolor plots. Privilege no hidden line
        removal when there are multiple objects in the plot.


That is

pcolor(peaks);hold on; contour(peaks,'k')

has the contour lines in front. However, the proposed change doesn't
seem to alter this, so this seem to be the right thing to do.. Now for
the missing cbtics.. In fact I see the cbtics with gnuplot 4.2.2 and not
with gnuplot 4.2 with the script as sent with "set pm3d implicit"..
"show cbtics" gives exactly the same information in both cases.. I
therefore suspect that this is a gnuplot 4.2 bug with user positioned
colorbars, though correct me if I'm wrong.. So I therefore propose to do
nothing about this. Patch attached
