As of previous commit, this is implied in a particular scenario. In fact, this is the one and only scenario that justifies the use of -a. Drop the option from the documentation. For backward compatibility, do recognize it, and retain the feature of ignoring the "container is stopped" error when set. Signed-off-by: Kir Kolyshkin <kolyshkin@gmail.com>
