[LLVMdev] Minor correction to the Visual Studio documentation

[Nathan Jeffords]

To get windows to execute python scripts without the extension, add .PY to
the PATHEXT environmental variable. Even though  I grew up programming DOS
and then windows, I personally quite like GnuWin32 as the windows command
line is generally lacking.
