[Emc-commit] upside-down: motion: treat a point as out of range when it it is not finite

[Jeff E. <gi...@gi...>]

motion: treat a point as out of range when it it is not finite

(not finite includes not only points at infinity, but also points
which are NaNs.  The existing comparisons were enough to weed out
infinities)
