This made Python 2's print behave like Python 3's print().

In some cases, where we had:

   from __future__ import print_function
   """Intended module documentation..."""

this will have the side effect of making the intended module documentation
work as the actual module documentation (i.e. becoming __doc__), because
it is once again the first statement in the module.

Using "#!/usr/bin/env python" is more portable. It still isn't ideal
though, as we should really use the python path found at configure
time. We do that in many places already, but some don't.

out of the samba4-deps.dot file.  Use like:

script/depfilter.py regpatch < samba4-deps.dot | dotty -

and then scratch your head and wonder why regpatch has to link with 3/4
of what it does.
