Hi, 

I can confirm that this behavior still exists in my current python versions (3.5.2 & 2.7.11). I'm happy to take a look at the code, but considering I made this account specifically to comment on this issue I assume someone else will want to, as well.

If you want to make sure this is still broken, just use any of the docs' reader and writer examples, adding a trailing escape char to the end.
