    Bug 798616 - Can't register amount greater than 9,000,000,000
    
    Because when loading the value the split in the xml backend doesn't yet
    have a parent so the code tried to convert to GNC_COMMODITY_MAX_FRACTION
    and if the numerator was larger than 10^10 that would overflow.
    
    To fix it this changes the "don't know" response to get_currency_denom
    and get_commodity_denom to GNC_DENOM_AUTO which will normally leave
    the denominator alone.
