I think that would depend on what the very first of those ~a thingies 
expands to.

The documented syntax and the existing demos both suggest the 'xy=' part 
to come rather immediately after "filledcurves".  The syntax only allows 
keywords like 'above' or 'below' in that place.  See "help with 
filledcurves" on current git head:

That would indicate this fraction of the command line rejected by 
gnuplot (from [1])

	w filledcurves fillstyle solid 0.1 xy=-1.0,0.0

would probably still work if it hat been

	w filledcurves xy=-1.0,0.0 fillstyle solid 0.1

instead.

That particular syntax was never explicitly supported.  It may just have 
happened to work anyway.  And now it doesn't.
