Proposal: Minor, semi-urgent fix

Append to the glossary, after "below zero instead sets them to zero." :

Any situation which would require a roll of DiceX when X is zero or lower always yields a value of 0 unless stated otherwise.

I think zero would be more appropriate than one for opposed rolls.
