Markus,

Thanks for the comments. As suggested by Wolfgang, the "-n" option was
pre-existing in the code before my patch.

I can investigate extending "-n" as described above; however, the caveat is
that the user knows that the values of some variables may have spaces. In
such a case, he/she might find the above example to not work as expected.

Anyway, hopefully Wolfgang can ACK the patch as is and I can look at
extending the "-n" option as another separate effort.

Regards,

Grant
