Comment 5 for bug 318517

There is a gedit-plugin available that does great things with tabstops and indets, called "elastic tabstops", see

It does what i asked for and many things more, but it is terribly slow. A few kilobytes of code will slow the editor down to be almost unusable. But maybe it is a good thing to build upon it.
