safe_mysqld.sh

  - set pid_file and err_log relative to DATADIR as specified in
    the my.cnf file, instead of the default value
  - do not pass safe_mysqld-specific options to mysqld
  - minor style changes (remove extra ; at end of line, make
    spacing more consistent, etc.)

manual.ja.texi
  - Turn off SCCS flag
