[Distutils] pypa.io PR to document the actual current spec update process

[Nick Coghlan]

Hi folks,

The "Specifications" section in the pypa.io developer's manual had
fallen behind the process we've actually been using in recent times,
so I've finally submitted a PR to bring it up to date:
https://github.com/pypa/pypa.io/pull/19

General questions about the change are best asked on the list, while
detailed comments on the specific wording in the PR are best submitted
through GitHub.

Cheers,
Nick.

P.S. See https://github.com/pypa/pypa.io/issues/11 for some additional
background
