Strange --- the code does something, since at least around version 4.0.
Could be a coincidence, i.e. it was already in the same shape usually 
created by 'set size ratio -1'.

The <xscale> and <yscale> parameters of 'set size' act on the 2D paper 
coordinate system, not on 3D at all.  The reason they appear to work the 
way they are is that the 3D-->2D projection set up by gnuplot always 
keeps the z axis vertical.

As I said before: you'll probably have to artificially set the x and y 
ranges to equal spans to make 'set size ratio -1' do something useful.
