feat(editor): from the end of the diverging track of a switch the line laid always goes on with the curve of the switch: a straight or a bend the other way after P4 begins with the transition out of the curve of the switch, as after a plain track on a curve, never with a jump of the curvature, whether laid through points, traced, dragged in the straight layout or joined to another free end. The transition is the one for the speed the curve of the switch allows with no cant (about 48 km/h at R 300, so 20 to 30 m), not for the speed of the line. A straight with no bend clicked on from such an end runs on the way the transition leaves, as far as the point clicked, not along the tangent at the end, which left no room for the transition. Where no transition fits, as for a straight shorter than it, nothing is laid and the status says why
