I'll push once the tree is open for 4.7.0 commits unless someone else
chimes in with other major issues that need to be addressed.



Tree re-opened after I left for a week away from the virtual world...
Now that I'm back and digging out of email, figured I'd sync this series
up with current top and push.

Please post a followup docs/news.xml article describing the change.

Thanks for this. I will cook a patch for this. :)

Tks -

John
