Change starting point

[manuelmeister]

It would be cool to rearrange the command list so that the starting point of a shape could be something more sensible. Like instead of between to "connecting" arcs, it could be at an edge. With this, i could reduce one or even two commands (as in the example picture i could replace the two arcs with one and the two line commands with a single line and a Z.
