Bug#17339009 --HELP DOES NOT PRINT ALL THE OPTIONS WHEN USED WITH MYSQL_SECURE_INSTALLATION

  Problem: mysql_secure_installation supports option-file
           options like --defaults-file, --print-defaults etc.
           which are not printed as part of help text.

  Solution: Added a call print_defaults() which prints the
            missing options. Also added a newline character
            at one place for better readablity.
