	epoch of perihelion as the final member of the array and the epoch
	of elements as the initial element in the array. This allows both
	epochs to be retained without confusion (since the penultimate

	change in the published interface.

	in the error message when failing to perturb the elements.

	* lib/Astro/Coords.pm (_iterative_el): Fix case when moon almost
