On the advice from Petr, the attached patch makes the pm3d plotting
explicit (ie must use splot ... with pm3d), and privileges no hidden
line removal when there are multiple objects displayed.. With this patch

[x,y,z]=peaks(10);
h1 = pcolor(x,y,z);shading flat;hold on;
[clev,h2] = contour(x,y,z,5);
for i = 1:length(h2)
  set (h2(i), "zdata", ones (size(get (h2(i), "xdata"))), "edgecolor",
"black");
endfor

works as expected..
