 > config unset help
 Command  unset  (Unset a configuration value (i.e. revert to the default,
 if any).)
                 help (Get help for command)
 Parameters:
     identifier (string, mandatory)
         The identifier specifies the config item. Child elements are
         separated with the '/' character. List indices can be
         specified with '[i]', where i is an integer specifying the
         index, starting with 0. Examples: 'Init/start_auth',
         'Auth/listen_on[0]/address'. If no identifier is given, shows
         the item at the current location.

 Given #3031 it currently isn't very useful to unset 'kind', but it
 shouldn't fail silently.
