Hmm, is this really a problem?

The call to editor->delete_entry() may not say the path's kind, but
the client knows the path's kind anyway, because the client has access
to the working copy. And the client knows that the server agrees
about path's kind, since the server and client already agreed on the
tree's state. When the server sends delete_entry(P):

   - If the client doesn't even have P anywhere, then clearly the
     client can ignore the call (?)

   - If the client does have P, then it knows P's kind, and it also
     knows the requested depth (because it's the client), so it can
     figure out whether or not to ignore the call.
