[Python-Dev] docs.python.org pointing to Python 3 by default?

I don't think this will be that bad. Most Python 3 documentation
pages apply to Python 2 as well. There may be features documented
that don't exist in Python 2, but it was always the case that
users of older Python versions had to watch for the
versionadded/versionchanged notices.

IMO, it would be good if each individual page had an "other
versions" section on left-hand block, or on the top along with
the "previous | next" links.

As for the amount of cross-linking, I suggest the following,
assuming 2.7 and 3.3 are the current releases:
1. 2.7 links to 2.6 and 3.3
2. 3.3 links to 3.2 and 2.7
3. all older versions link to "newest", i.e. 3.3.

I understand that this would require a custom mapping
in some cases. It would be best if Sphinx could already
consider such a mapping when generating links. Failing
that, we can also do the custom mapping in the web
server (i.e. with redirects).
