I beleive that the vast majority of python[23] users will be fine with the 
latest version of the relevant branch.
Considered that and also not to over complicate things I propose to make 
python2/python3 symlink only for the latest version: python2 -> python2.7
and python3 -> python3.2 for now.

And leave python31, python25, python26 untouched.  Users who really need older 
versions of python should explicitly require python version during startup.

If it is OK for you, I can work out the final patch.
