Yeah agreed. As far as I see it, the level will only be 0 before the
first WJB_BEGIN_OBJECT and those appear to be the first thing in the
document, so we'll only indent level 0 once and everything else will
be > 0. So, it also seems to me that the additional check is more
likely to cost more than it would save.
