2. Pick several points.
3. Start Sketcher_CreateLine.
4. Only one point from the spline is visible.
5. Pick two points for the line.
6. The other points of the spline also become visible.

It looks like there is a mess with the transactions when creating the spline. After clicking the first point a transaction "Add Knot Point" is added to the Undo list. When finishing it then this transaction is committed.

The behaviour of most other commands is different: they add a transaction after finishing the creation of the geometry.
