* Issue #22457: Honour load_tests in the start_dir of discovery.

2014/10/31 - 0.7.1

Fix for 0.7.0 being broken. Also switches from both manual and entrypoint
scripts to just entrypoint scripts to reduce the possibility of similar
oversights in future.

This release contains backports from cPython 3.5 of all (I think) commits since
2010, as of today.
