commit 21501b42c55182861ad7afe82d5267f442722e03

    Do not use embedded copy of ssl.match_hostname, when possible
    
     The system python has the necessary features backported, since 2.7.8-7 (and
     221a1f9155e2, releasing in 2.7.9, upstream). However, alternative python
     implementations don't, yet, and urllib3 is used by pip in virtualenvs.
