Don't bother, really I was just whining.  Now that I'm more awake,
I went ahead and modified my wordlist backup procedure so it does
a bogoutil -d | bogoutil -l, which works for either type of database.
I also inserted an awk step similar to the one I use when extracting
the ACME spamwords, so now my backup copies will be much smaller but
still functional.
