...and here's a version that actually works! (previous one just assigned
python, and not leo, to the file type).

'''Tell Windows how to handle .leo files, enables double clicking on them
to open.
To run: in Leo make this the active node and press [Ctrl-B] (execute-script)
It opens a command shell and uses `assoc` and `ftype` commands to inform
Windows
where python.exe and the Leo launch script is. It's the equivalent of:
assoc .leo=Leo.File
ftype Leo.File="B:\Python27\pythonw.exe"
"B:\apps\leo-editor\launchLeo.py" "%1" %*
Requires elevated User Account Control (UAC) priviliges.
