Hi all,
The attached patch fixes a regression and is a patch from Steve. I have
regression tested it and provided a test case. It is fairly simple and
I will commit under the "simple" rule in a little while.
Thanks Steve for Patch. Thanks Harald for helping me get back up to
speed on the git magic.
Regards,
Jerry
