WITH NON-STANDARD PORT NUMBER

                  Problem:
                  ------
                  main.mysqld--help-notwin fails with result content
                  mismatch when MYSQL_TCP_PORT value is different from
                  the standard port number which is 3306.

                  Fix:
                  ---
                  Masked the result of the port number with #### by
                  adding "s/^port \d+/port ####/;" in mysqld--help.inc.
