I intended it mainly for the case when a script fails inside set multiplot.

For binding hotkeys. Left and right arrows could have different bindings in 
plot and splot, e.g.
bind 'Left' if (GPVAL_PLOT) shift xrange left; replot; \
	else builtin_rotate_left

Good idea, I'm adding it. Having GPVAL_{S}PLOT is necessary anyway, since 
the plot command can start with "p ", "plo ", "sp ", ...

This would be nice. I guess it would need printing the "show output" into a 
text buffer.
