pip 9 offers upgrades to prereleases

[mgedmin]

• Pip version: 9.0.3
• Python version: 2.7.14
• Operating system: Ubuntu 17.10

Description:

Any pip command says

You are using pip version 9.0.3, however version 10.0.0b2 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

I'm not sure it's a good idea to offer upgrades to pre-release versions? Anyway, the suggested command doesn't work (because it needs --pre to allow upgrades to pre-release versions):

Requirement already up-to-date: pip in /home/mg/.venv/lib/python2.7/site-packages
You are using pip version 9.0.3, however version 10.0.0b2 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

Thanks for reporting this! It's only likely to be an issue for a relatively short period (pip 10 final is due in just over a week) but it's good to have the problem recorded so that we can ensure it doesn't crop up for future betas.

Relevant line is this. We'd want to filter out pre-releases here.,
