The PX4BuildBot extracted the comments from the lines following
the class line which says "Plane" as the class. To avoid the
confusion for the bot I moved the comment further down.

mc_pos_control_main smooth takeoff: enable position-xy/yaw control once above 0.5m from takeoff reference

just keep thrust vector pointing upward

smooth-takeoff. This is only required if someone writes a FlightTask where both position
and velocity setpoints are finite
