This seems to be still not possible. I've also tried to manually set 'RightEdge' in PSPad.INI. That worked fine, but only until my source file was externally changed. After I've confirmed that I wanted to reload the file, the vertical line disappeared. So manually editing PSPad.INI is not a solution (at least not until the reload problem is fixed).
