env

From the man page for env:

The historic - option has been deprecated but is still supported in this implementation.

What does the "historic - option" do?

In particular, why does it change which version of python is run?

~:$ env python
Python 2.6.5 Stackless 3.1b3 060516 (release26-maint, Mar 24 2010, 09:47:07)

but:

~:$ env - python
Python 2.5.1 (r251:54863, Feb  6 2009, 19:02:12)
