If instead of a chain of Lines each defined by two Points you use a
Spline or BSpline defined by multiple Points then those Points aren't
necessarily used in the mesh, which I think is the behaviour you're
after.  Try the attached example, running it with

  $ gmsh -2 -clscale 5 octagon.geo

and then changing 5 to smaller numbers.
