Hi David (N), attached my first try. If the markup-property full-length is set #t, some calculations ensure that no space occurs at line-end/begin. Some dashes will only be partly visible, but I think its ok. In addition I wrote a top-level-testing-function to minimize typing. Some comments are added. But I have no clue why I need 13 as a factor in a specific calculation. What do you think? -Harm
