I think that's a valid possible situation which could result in a
change. however, I think it's much less likely than it used to be
because we'd have to accidentally have used query_jumble_ignore,
whereas before all the struct parsing stuff went in, we could have
just forgotten to jumble the field when adding a new field to a parse
struct.
