Check whether an update to currentAllocation satisfies
proposal.want. Note that this is half of the offer safety
check; whether the allocation constitutes a refund is not
checked. The update is merged with currentAllocation
(update's values prevailing if the keywords are the same)
to produce the newAllocation. The return value is 0 for
false and 1 for true. When multiples are introduced, any
positive return value will mean true.
