SHOW CREATE TABLE fails Underlying table names, that merge engine fails to open were not reported. With this fix CHECK TABLE issued against merge table reports all underlying table names that it fails to open. Other statements are unaffected, that is underlying table names are not included into error message. This fix doesn't solve SHOW CREATE TABLE issue.
