For nodes in excluded areas, we don't necessarily want to remove them from the pointer, but we do want to increase the number of pieces in the segment in case those excluded area nodes go down. To do that, we increase the number of pieces repaired by the number of pieces in excluded areas. Change-Id: I0424f1bcd7e93f33eb3eeeec79dbada3b3ea1f3a
