Sadly I spoke to soon :-(  The error now, in a clean and up-to-date
chroot after "apt install python-pip", is:

# python -m pip --help
Traceback (most recent call last):
  File "/usr/lib/python2.7/runpy.py", line 163, in _run_module_as_main
    mod_name, _Error)
  File "/usr/lib/python2.7/runpy.py", line 111, in _get_module_details
    __import__(mod_name)  # Do not catch exceptions initializing package
  File "/usr/lib/python2.7/dist-packages/pip/__init__.py", line 31, in <module>
    from pip.vcs import git, mercurial, subversion, bazaar  # noqa
  File "/usr/lib/python2.7/dist-packages/pip/vcs/mercurial.py", line 9, in <module>
    from pip.download import path_to_url
  File "/usr/lib/python2.7/dist-packages/pip/download.py", line 40, in <module>
    from pip._vendor import requests, six
ImportError: cannot import name requests

# pip --help
Traceback (most recent call last):

Maybe pip.dependencies and dirtbike are broken, which means
${python:Depends} isn't functioning properly?  Applying my patch
allows both "python -m pip --help" and "pip --help" to succeed.  From
what I can tell the reason is because python-certifi, python-requests,
python-urllib3, and their dependencies are still not installed for
python-pip-9.0.1-2.2.

Kind regards,
Nicholas
