 This happens only for mesh refined runs and on reflevel>0 ie in the buffer
 zones. This happens only if the "useghosts" option is not set (it is unset
 by default). This behaviour is technically allowed by the docs since Slab
 only claims to fill in ghost zones and the outermost points are not ghosts
 but buffer zones (though Carpet disagrees somewhat on that in that it does
 not count them in buffer_width).

 Anyhow, this does not to my knowledge actually affect RotatingSymmetryXX
 which are the most prominent users, at least their poison_boundaries
 option does not seem to pick this up.

 To test, run the attached modified slabtest.par test file whcih fails in
 the identity test for level 1 unless useghosts=1 is used in slabtest.c
 (and fails int the skip-every-second point test if it is used).
