Turn on H233 and start using print function

As much as anything, I'm just tired of seeing a bunch or piecemeal
fixes.

Note that we *need* to include

   from __future__ import print_function

in order to support things like

   print()  # Would print "()" (the repr of an empty tuple) otherwise
   print(foo, end='')  # Would SyntaxError
   print(bar, file=sys.stderr)  # Would SyntaxError
