Whoops. My error. For some reason I had it in my memory that I should "not" have a blank line at the end of the rootfile.
I realise now that I "should" have a blank line at the end of all of them. Will put a note about this in my list of things that I should pay attention to getting right.
Sorry. Next sets of patches will not have that problem.

Adolf
