Keep nulls in a verinum and keep as string when padding is mod 8. 

For diagnostics and to know what is really going on in the compiler
we need to keep any NULL that is in a verinum string or when
displayed as/converted to a string.

When padding a verinum string if the padding is in multiples of eight
then keep the string property.
