Message 149945 - Python tracker

I checked the submitted patches from the issues against the large patch by eye. Guilherme's patches in these separate issues have the same contents: issue1207589, issue1612262, issue1721083, issue6699, issue3359.

The large patch updates issue964437, but the "view_file" change is outdated. 

I wrote more recent patches for issue4832 and issue6698.
