ColumnBalancer: need to examine lines that protrude into the flow thread portion.

We cannot skip a line that starts before the flow thread portion of interest,
if it ends inside the portion.

Some extra care is needed to avoid regressions here: The part of a line that
starts before the multicol container itself needs to be ignored, or we risk
overstretching the multicol container.
