Comment (by robe):

 should be fixed at r13593 by reverting back to using sphere distance and
 put a note in docs that its based on sphere distance.  I still need to put
 in a note in docs saying use ST_Distance for accurate measure, but that
 will come with an example.  Also have changed the tests to avoid using
 rank in conjunction with index tests at r13594, I'm not sure why that
 forces it not to use an index.  Have to double check that one.  That
 doesn't make sense to me.
