Ever since 6.0 pip now implicitly warns users on every invocation if
there is a newer version of pip available on PyPI (assuming they are
not in some constrained environment that cannot access pypi.python.og).

I fully expect Debian to upgrade to pip 8.0 in the near future in sid,
it obviously want make it back to Jesse though except via back ports. This
is mostly an outlier I think, pip 6+ really ramped up the number of things
that pip bundles, plus with it getting bundled with pip it created a bit
of a contentious situation with Debian. I believe that the excellent Barry
Warsaw is close to having that ironed out and pip 8.0 ready to land, and
future upgrades should be pretty painless.
