Appearance of S-curves

[Thomas Morley]

Hi,

currently we print beziers for slurs, ties, etc as a bezier-sandwich,
where second and third control-point of the second bezier is the same
amount apart from the ones from first bezier's control-points.
This is fine for the all usual cases.
Though, is it ok for S-curves as well?
Attached an image with default behaviour and "crossing" bezier-curves.

I'm undecided which I'd prefer.
Opinions?

Thanks,
  Harm
