except that I would have placed it a bit later. I'll do it and commit.
1) It seems your patch did not remove my block, so now those four lines
are in two places.
2) In fact, I originally tried putting it later in the fn, which looks
more natural given the existing code. However, I found that it does not
have any effect if it is any later than it is. Experimentally, I
determined that it has to be before the line:
$self->push_top_formatter('_Root_context');
