I'm sorry, but this issue looks like a bug in pip, not in Python. Please report the issue at https://github.com/pypa/pip/issues 

Oh, I'm sorry, I read too fast. I didn't notice the pull request. It seems like a real bug in Python 2.7.

In fact, it seems like I introduced a regression in bpo-6393, commit 94a3694c3dda97e3bcb51264bf47d948c5424d84.

I backported this commit, but I didn't notice the bug in the code... In fact, this commit was followed by the commit 6a448d4c2eac16af4c451b43c6dc46cf287b1671.

ok, is this a valid fix then?
