Subject: r21321: - Allow pruning all of the children of a node without
 removing the node   itself.

- By default, create only one meta column if only the tree is displayed.  If
  additional columns are displayed, then put all of them in a separate meta
  column, and the tree in the first meta column by itself.
(This used to be commit 6c86cd416b64e97071f6bbd2d63f33a950a28ec0)
