The problem is not in the "close" option. The problem is that Octave 
issues before each "plot" this command:

	set terminal x11 close enhanced title "Figure 1" size 560,420
	position 300,148

i.e. Octave wants to reset size and position. However, I think that the 
size+position options should be added only if user has explicitly 
"set(gca,..., size/position, nnn)"; otherwise, these values should not be 
passed to gnuplot and the positioning should be done by the window manager 
and user's mouse movements. The default value of size/position in Octave 
should be "auto" or "default" but not an explicit number.

By default, Octave should ask for
	set terminal x11 enhanced title "Figure 1"
as it has been doing until now.
