I think that patch was for a different problem.

Octave 2.0.13 fixes the blank page problem, but you still get 3 pages
for something like

  plot (x1, y1, x2, y2, x3, y3);

The problem is with the implementation of the plot function.  It
should be possible to fix, but it's not a high-priority project for
me.  Perhaps someone else would like to tackle the problem and submit
some patches?

In any case, a workaround is to do the plotting to the screen, then
issue a replot command:

  plot (x1, y1, x2, y2, x3, y3);
  gset term postscript
  gset output "tmp.ps"
  replot

Then you should get only one page.  If you don't want anything showing
up on the screen, try something like this:

  gset term postscript
  gset output "/dev/null"
  plot (x1, y1, x2, y2, x3, y3);
  gset output "tmp.ps"
  replot
