pangofc-shape: Fix potential array overrun
If this loop adds the final feature to the features array, the start and
end assignment for the next feature will drop off the end of the array.
I don’t think the assignments are necessary, since num_features stores
the number of elements in the array (so it doesn’t need to be
terminated), and the start and end elements are assigned each time a
feature is parsed.
