      Quote a string for use as a command line argument in DOS or Windows.
  
      On windows, before a command line argument becomes a char* in a
      program's argv, it must be parsed by both cmd.exe, and by
      CommandLineToArgvW.
  
      If for_cmd is true, then this will quote the string so it will
      be parsed correctly by cmd.exe and then by CommandLineToArgvW.
  
      If for_cmd is false, then this will quote the string so it will
      be parsed correctly when passed directly to CommandLineToArgvW.
  
      For some strings there is no way to quote them so they will
      parse correctly in both situations.
