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.
