+Subject: [PATCH 3/3] readProjectTree: provide root node to append
+ to
+
+append_child() is not supposed to work on an empty tree,
+and I couldn't find any initialization before its use.
+All inserted nodes seemed to end up below tree_node::feet
+(or something) and were not cleaned up by the destructor.
+
+Using insert() to create a dummy node for others to be
+children of fixes the leak.
