Comment 4 for bug 1379998

With a current version of tox, running 'tox -e pep8' in an up to date checkout of openstacl/oslotest's master branch reveals that cmdargs did 'pip install --pre -r requirements.txt -r test-requirements.txt' which would explain why oslotest tox runs are ending up with a beta of Sphinx (normally we don't use --pre). This seems to be because oslosphinx doesn't override install_command in its tox.ini.
