  1) there is useless 'u' in the wrong info when execute a wrong glance command:
  root@45-59:/opt/stack/devstack# glance wrongcmd
  usage: glance [--version] [-d] [-v] [--get-schema] [--no-ssl-compression] [-f]
                [--os-image-url OS_IMAGE_URL]
                [--os-image-api-version OS_IMAGE_API_VERSION]
                [--profile HMAC_KEY] [--insecure] [--os-cacert <ca-certificate>]
                [--os-cert <certificate>] [--os-key <key>] [--timeout <seconds>]
                [--os-auth-url OS_AUTH_URL] [--os-domain-id OS_DOMAIN_ID]
                [--os-domain-name OS_DOMAIN_NAME]
                [--os-project-id OS_PROJECT_ID]
                [--os-project-name OS_PROJECT_NAME]
                [--os-project-domain-id OS_PROJECT_DOMAIN_ID]
                [--os-project-domain-name OS_PROJECT_DOMAIN_NAME]
                [--os-trust-id OS_TRUST_ID] [--os-user-id OS_USER_ID]
                [--os-username OS_USERNAME]
                [--os-user-domain-id OS_USER_DOMAIN_ID]
                [--os-user-domain-name OS_USER_DOMAIN_NAME]
                [--os-password OS_PASSWORD] [--key-file OS_KEY]
                [--ca-file OS_CACERT] [--cert-file OS_CERT]
                [--os-tenant-id OS_TENANT_ID] [--os-tenant-name OS_TENANT_NAME]
                [--os-region-name OS_REGION_NAME]
                [--os-auth-token OS_AUTH_TOKEN]
                [--os-service-type OS_SERVICE_TYPE]
                [--os-endpoint-type OS_ENDPOINT_TYPE]
                <subcommand> ...
  glance: error: argument <subcommand>: invalid choice: u'wrongcmd' >>>>ISSUE

                  [--os-tenant-name <auth-tenant-name>]
                  [--os-tenant-id <tenant-id>] [--os-auth-url <auth-url>]
                  [--os-region-name <region-name>]
                  [--os-identity-api-version <identity-api-version>]
                  [--os-token <service-token>]
                  [--os-endpoint <service-endpoint>] [--os-cache]
                  [--force-new-token] [--stale-duration <seconds>] [--insecure]
                  [--os-cacert <ca-certificate>] [--os-cert <certificate>]
                  [--os-key <key>] [--timeout <seconds>]
