And I have to wonder why git-daemon serves under py2.7, but really
wants receive-pack to be allowed under 3.4. Maybe it's a repository
override which for some reason doesn't work in py3.4 ? Maybe because
the change is not flushed ?

Kind of tackling the tasks step by step, picking low-hanging fruit first,
or the ones that everyone depends on

More to come, especially when it's about strings

There is more work to do though, as many imports are still incorrect.
Also, there are still print statements

autopep8 -v -j 8 --max-line-length 120 --in-place --recursive

This could however, introduce a chance of an assertion hitting once again
as it has been commented out for quite a long time. Now it's back in a changed form
though, and once again tries to make sure we get proper results

* GIT_PYTHON_TRACE now behaves correctly for fetch, and pull (i.e.  if as_process is used)
* Improved parsing of fetch head information

However, there is still a messy bit that tries to bring together fetch progress information
with fetch head information. Even though it works now, an alternative implementation should
be attempted.

Commandline was
autopep8 -j 8 --max-line-length 120 --in-place --recursive --exclude "*gitdb*,*async*" git/
