[Jonathan Tedds]

Patricio is surely right? There is a simple and added value to
the logic of the substring approach so please can someone provide the
justification that was put forward for not using it? A bit of extra coding
effort (if even needed as others have alluded to?) will keep the interface
to the more general user at a more intuitive level.

Thanks,
Jonathan
