In other words, we've always defined "revision" and "transaction" as
mutually exclusive terms -- a tree is either one or the other.

Now we're publically redefining the word "transaction" to be a
*superset* of the definition of "revision." That is, all trees are
transactions. Some of them just happen to be revisions.
