Fixed overview section generation.

The regression was introduced with one of recent contributions. My guess is the contributor was using older code base and didn't update before issuing pull request. The same issue repeated second time, to prevent further regressions, I added a comment to source code specifically guarding against changing affected lines. Not the best approach, but at least something until 3.0 is out...

Most often this happens with folks wanting to bring in better HeaderDoc support, but it brakes "standard" appledoc way of dealing comments. While I symphatize with ideas of supporting as wide audience as possible, native appledoc users are still larger audience than HeaderDoc, so please find another way. My suggestion would be via cmd line switch that would change behavior from appledoc to HeaderDoc, then opt out with an if statement.
