Glad to here that's working for you. Unfortunately this doesn't work for
me. I reordered the lines a bit because I think that the override
changes the line-width property of wordwrap-string. But the reordering
doesn't change the ouput. The text crosses several measures in this
example. I thought that \with-dimensions defines the extend of the
markup. But this doesn't affect the measure width.
