Depending on whether transformers contains functions to modify the
line break information, the column multi_line is updated (after
the line break information is modified) and
the rest of the transformers is applied afterwards, or (if line break
information is not to be modified), all transformers are applied in one
step. The former requires two pre visits and one post visit, the latter
only one pre visit.
