+This will import foo from d, but then it unexports foo from d.
+
+Not quite data loss, because it does honor numcopies and the local copy
+remains. But bad.

+The problem seems to be that it assumes it's merged d/master into master, but
+that does not happen since master is not the current branch. And so it then
+updates d to look like master. --[[Joey]]
