about_nil.rb  tests

I am totally open to reprimands / corrections  / admonishment about how these commits were done.   I think it was a mistake to merge master because now the older commits from master are showing up in this new branch " much ado about nil "    ..... and I'm thinking they shouldn't. So I will accept my punishment. I will keep doing these as I can; weaving it into my work days over the next week or so.
