Comment:

 OK, this is changed in main at f885c3354. ST_GeometryN(empty) will return
 NULL for all values of N, which matches up with ST_NumGeometries(empty)
 returning 0 for all values of empty, collections and singletons both,
 since there's no in-range value of N when the count is 0.

 I have left the stable branches alone in the interests of preserving
 existing behaviour.
