+short extension.  Any binding that isn't the Hydra's head vanquishes the
+Hydra.  Note that the final binding, besides vanquishing the Hydra, will still
+serve its original purpose, calling the command assigned to it.  This makes
+the Hydra very seamless; it's like a minor mode that disables itself
