This does not work reliably for me. Sometimes I can break a quote in two without any trouble, but no further. Sometimes I only can break them at ends of the lines (that is, the end of text ... not if the line ends with space). Or it works at certain spots in the text, and not in others. Sometimes it doesn't work at all. I have no idea why each of these scenarios happen when they do. Is there a trick to it?
