plot -Sf not following -W+s

[KristofKoch]

Description of the problem

When using -Sf together with -W+s the symbols aren't placed along the bezier spline. Maybe related to #1165? I have the feeling that this is somewhat related to bezier splines being a pure PostScript thing.

Yes, cannot be done. PR coming to fix docs and prevent this combination.
