Eh, tomato, tomahto. If you assume that someone will strip leading
zeroes consistently, the Oracle approach makes sense. That would be a
reasonable assumption to make; why would I strip the zero off the month
but leave it on the day? So, in the unusual case that you want to do
such a thing, you are asked to use a second occurrence of FM to turn
zero suppression back off.
