Sigs and catchwords between verse lines were showing up run into the line; the main reason for this was that verse lines are rendered with their linebreaks before them, rather than after (for various reasons), whereas the novels have simple linebreaks in the original text, at the end of lines. I've now added a bit to the XSLT which detects when an <l> tag precedes them directly, and in that case an extra <br> tag is emitted.
