It has been pointed out to me that the patch has a minor, yet basic
error in the planning. This has now been corrected in this patch.

It appears that my midnight-patch submission was not such a good idea
after all. My full and sincere apologies to anybody that tried and
failed on that patch. To err is human...

I have also now filled the gap for when all relations are excluded,
mentioned as question 1 in my original post.

I have now re-tested the patch against cvstip...
The special tests files are unchanged.

Performance tests and comments welcome.

Best Regards, Simon Riggs
