Remember that we're already using this post-update technique for
'deleted' items. After the client finishes applying the tree delta to
the working copy, it looks for 'deleted' items -- if any exist, the
logic is "huh... well the server didn't re-add them, I guess they're
really supposed to be gone for good, then."

All we're doing now is extending that same idea to 'missing items':
"if the server didn't re-add them, then they're really supposed to be
gone for good." It seems like a perfectly consistent strategy to me.
