Don't print potentially verbose help messages in case of usage errors, but print only the usage error followed by a pointer to the command's help. This aligns with Docker. ``` $ podman run -h flag needs an argument: -h See 'podman run --help'. ``` Signed-off-by: Valentin Rothberg <vrothberg@suse.com> Closes: #1379 Approved by: rhatdan
