      public List<String> getCommandLine(String executable, String[] arguments)

      Specific implementation that quotes all the command line.

      Workaround for

      From cmd.exe /? output:

            If /C or /K is specified, then the remainder of the command line after
            the switch is processed as a command line, where the following logic is
            used to process quote (") characters:
            1.  If all of the following conditions are met, then quote characters
            on the command line are preserved:
            - no /S switch
            - exactly two quote characters
            - no special characters between the two quote characters,
            where special is one of: &<>()@ˆ|
            - there are one or more whitespace characters between the
            the two quote characters
            - the string between the two quote characters is the name
            of an executable file.
            2.  Otherwise, old behavior is to see if the first character is
            a quote character and if so, strip the leading character and
            remove the last quote character on the command line, preserving
            any text after the last quote character.

      Always quoting the entire command line, regardless of these conditions appears to make Windows processes invoke successfully.
