o Example: baseCE << b <<< q << c * nextCE(X,2)
|

? There are 2 secondary items: b, c. Fit them into the secondary gap.
|

Then fit q into the tertiary gap between b and c.

o When incrementing primary values, we will not cross high byte
|
|
boundaries except where there is only a single-byte primary. That is to
|
|
ensure that the script reordering will continue to work.
