OK, so they are ignored, *but* i still think that asserting on it is vital
because in the other case (= fixed length set by user or even worth, line
length defaults to m_default_line_length cause user did *not* set a line
length at all) it would mean that the formatting simply silently fails.
Not very nice form a users point of view!
