Heh. I must have edited the post five times to add more stuff. After
saying "Find out in the next post!" I wasn't about to start a new post!

One trivial bit I thought of adding that I'll add now: The person who
raised the question of the meaning of the grid lines is an ex-patriot
Scot living in southern England. I talked with him on the phone not
very long ago. He hardly has any Scottish accent left!
