still on octave and gnuplot aqua

[Andrea D'Amore]

Hello,
I have Aquaterm and gnuplot working with terminal set to "aqua" as  
default even without GNUTERM environment variable but when I call a  
plot from octave 3.0.1 gnuplot uses X11.
If I set GNUTERM to aqua then an octave plot() calls gnuplot in  
aquaterm.

Is this an octave issue? Why does gnuplot use X11 when called from  
octave but it uses aqua when called from cli?
