Backport of the print function, using a __future__ import.
This work is substantially Anthony Baxter's, from issue
1633807. I just freshened it, made a few minor tweaks,
and added the test cases. I also created issue 2412,
which is to check for 2to3's behavior with the print
function. I also added myself to ACKS.
