Good point. In that case I would change the fourth parameter to sweep angle. 
It would be a value between 0 and 360 and either positive or negative to 
indicate the extant of the arc and its direction of travel.

KiCad has a method for specifying the data for an arc so this is more just 
ideas of other ways it can be done.
