docs: def escape_for_cmd_exe(arg):
      '''
      Escape an argument string to be suitable to be passed to
      cmd.exe on Windows
  
      This method takes an argument that is expected to already be properly
      escaped for the receiving program to be properly parsed. This argument
      will be further escaped to pass the interpolation performed by cmd.exe
      unchanged.
  
      Any meta-characters will be escaped, removing the ability to e.g. use
      redirects or variables.
  
      Args:
          arg (str): a single command line argument to escape for cmd.exe
  
      Returns:
          str: an escaped string suitable to be passed as a program argument to cmd.exe
