        // 1) wrap the string in quotes
        //
        // 2) double-up quotes - i.e. " => ""
        //
        //    this is different from the libuv quoting rules. libuv replaces " with \", which unfortunately
        //    doesn't work well with a cmd.exe command line.
        //
        //    note, replacing " with "" also works well if the arg is passed to a downstream .NET console app.
        //    for example, the command line:
        //          foo.exe "myarg:""my val"""
        //    is parsed by a .NET console app into an arg array:
        //          [ "myarg:\"my val\"" ]
        //    which is the same end result when applying libuv quoting rules. although the actual
        //    command line from libuv quoting rules would look like:
        //          foo.exe "myarg:\"my val\""
        //
        // 3) double-up slashes that preceed a quote,
        //    e.g.  hello \world    => "hello \world"
        //          hello\"world    => "hello\\""world"
        //          hello\\"world   => "hello\\\\""world"
        //          hello world\    => "hello world\\"
        //
        //    technically this is not required for a cmd.exe command line, or the batch argument parser.
        //    the reasons for including this as a .cmd quoting rule are:
        //
        //    a) this is optimized for the scenario where the argument is passed from the .cmd file to an
        //       external program. many programs (e.g. .NET console apps) rely on the slash-doubling rule.
        //
        //    b) it's what we've been doing previously (by deferring to node default behavior) and we
        //       haven't heard any complaints about that aspect.
        //
        // note, a weakness of the quoting rules chosen here, is that % is not escaped. in fact, % cannot be
        // escaped when used on the command line directly - even though within a .cmd file % can be escaped
        // by using %%.
        //
        // the saving grace is, on the command line, %var% is left as-is if var is not defined. this contrasts
        // the line parsing rules within a .cmd file, where if var is not defined it is replaced with nothing.
        //
        // one option that was explored was replacing % with ^% - i.e. %var% => ^%var^%. this hack would
        // often work, since it is unlikely that var^ would exist, and the ^ character is removed when the
        // variable is used. the problem, however, is that ^ is not removed when %* is used to pass the args
        // to an external program.
        //
        // an unexplored potential solution for the % escaping problem, is to create a wrapper .cmd file.
        // % can be escaped within a .cmd file.
