Heh, your question really made me think...

To be honest, I'm not sure, but I'd look at how the vertical line numbering is implemented and go from there. Here's the source for the AbstractDecoratedTextEditor. Take a look at createLineNumberRulerColumn(), and see if this takes you anywhere.

My guess is, if it's doable, it's probably not an easy task. Good luck :)!
