Fair enough. We'll keep the behavioral change then.

What I think I'll do for the moment is make them independent options so
far as the implementation is concerned, but have the command line switch
processing do
/* --create implies --set-db-properties, for now anyway */
if (dopt.outputCreateDB)
dopt.set_db_properties = 1;
If somebody actually asks for --no-set-db-properties, we can add that
later.
