This turns out to be the most important part. A conversion using
"format-5" ends up as 1.4MB, down from the old 2.6M. So it would seem
that we were indeed duplicating far too many entries.

So hats off to you Robert, your change makes a big difference. (It
changed the number of lines from 34.7k down to 25.5k)
