Hello!

As part of an effort to ease the contribution process and adopt a more standard workflow pip has switched to doing development on the master branch. However, this Pull Request was made against the develop branch so it will need to be resubmitted against master. Unfortunately, this pull request does not cleanly merge against the current master branch.

If you do nothing, this Pull Request will be automatically closed by @BrownTruck since it cannot be merged.

If this pull request is still valid, please rebase it against master (or merge master into it) and resubmit it against the master branch, closing and referencing the original Pull Request.

If you choose to rebase/merge and resubmit this Pull Request, here is an example message that you can copy and paste:

*This was migrated from pypa/pip#1467 to reparent it to the ``master`` branch. Please see original pull request for any previous discussion.*

Hi @BrownTruck,
it looks like many things changed since our (@z4r and me) proposal, and it seems already fixed by the behaviour at:
