I figured I'd wait to see how quickly they might land in Jef's tree - so while I referenced
the last version in my coverity_scan branch, I hadn't pushed them to the actual 
Subsurface-branch (and not referenced them from Subsurface master).

I'll kick off a new Coverity build with that latest version in a moment.

Thanks
