A very minor adjustment of xlabel and ylabel is needed.
The following example should show the problem:
octave:1> plot([1:200])
octave:2> xlabel('this is xlabel');
octave:3> ylabel('this is ylabel');
octave:4> title('this is the title');
octave:5> print "test01.ps"
=========================
The plot looks just fine with the x and y labels positioned
correctly.  However, the PS file has the x and y labels written
too close to the actual x and y axes so that the text overlaps
the numeric scale values.

I have tried a few other plots and this is the only problem that
has come up.
