Not sure. In a script it's possible a lot of changes happen in sequence, until the next redraw. So, give it a try. I was also wondering if we need a "flush" command for the changes, in case a redraw is undesired but the listeners should be invoked. Another possibility is to automatically flush before adding a change that is above a previous one AND it changes the line count. That's when keeping track of line numbers becomes difficult. -- If all you have is a hammer, everything looks like a nail.
