Comment(by rlaager):

 I'm accepting this patch with some modifications to the messy string code
 around the part you changed. I don't have a Zephyr account (though I'm
 supposed to be getting a test one soon), so I'd really love it if you
 could test my changes (which I will attach).

 If you're not already listed and would like to be credited in the
 COPYRIGHT file, please let me know which real name to use.
