Request: undo & redo should affect lines

[ThinkSalat]

If I alter some lines and then hit undo, the highlight stays there even if the code is back to what it originally was. Perhaps there could be an option to make it so hitting undo removes the last highlight?

This confuses even more if you add line and then undo. In this case it will highlight wrong line.
