Adding the shebang line on Windows would be excellent practice.  In
fact, Python 3.3 and later ships with the Python Launcher for Windows
[1] which is very effective at reading the shebang line and executing
the script with the proper Python installation.  It makes using Python
2.x and 3.x on the same Windows machine much less painful, as well as
not having to add anything to the PATH and being able to launch
whichever interpreter you want with a single command.
