Note that this function may not skip over invisible text that is so
because of text properties and immediately follows a newline. If
it would, function reseat_at_next_visible_line_start, when called
from set_iterator_to_next, would effectively make invisible
characters following a newline part of the wrong glyph row, which
leads to wrong cursor motion. */
