See my workaround:

set log x; set nolog y; jay = {0,1}; p(x) = jay*x
set xrange [.1:10]; set grid
model(x) = 1/((1+p(x))*(1+p(x))*(1+p(x)))
plot arg(model(x)) smooth unwrap,\
"uninteresting.txt" using 1:(arg(model($1))) with lines  smooth unwrap title "workaround"

where uninteresting.txt contains .1 1 .2 1 etc 10 1

Is it a bug or a feature?
