I thought about this, but if the nulls aren't entirely random, then they
aren't entirely null.  If we're already talking about digraphs and
trigraphs, then adding in a null that can only appear in the context of
certain letters is equivalent to adding additional symbols to the table.

For example, if Q is null, but it can only appear before O, then effectively
QO = O.  The Q isn't actually empty of meaning, it can be seen as part of
another symbol in the table.

I'll post more later, including my program to identify nulls.
