    Modify the behavior of CommandLineTool to generate a single string
    containing a shell command line. Each item in the argument list must be
    joined into a string separated by single spaces and quoted to prevent
    intepretation by the shell, unless CommandLineBinding for that argument
    contains shellQuote: false. If shellQuote: false is specified, the argument
    is joined into the command string without quoting, which allows the use of
    shell metacharacters such as | for pipes.
