The default behaviour of clojure.data.zip.xml is to automatically match
for the children nodes for a given location (by dissoc no-auto=true). To
make it consistent, move-node now uses children-auto to get the moved
node so the returned location is also auto for next tag match.
However, I need to think more carefully about whether the default should
be auto or not. If we want to match XPath, auto should always be false.
