Problem with get_in_function_call partly fixed in dev

I created this test, because I thought it is now fixed in the dev branch. But it works with 3.2, 2.7 not with 2.5, 2.6. The code itself runs on all python versions. @davidhalter: I will investigate further, if you say its worthwhile.

I opened this as a pull request with the idea that it will be continuously tested against dev, I hope travis behaves this way.
