ipcs man page describes invalid -b option in RHEL 5

Issue

• Manual page for ipcs documents the following OPTION:

  -b     Write information on maximum allowable size. (Maximum number of bytes in messages on 
         queue for message queues, size of  segments for shared memory, and number of semaphores in 
         each set for semaphores.)
  

• Actual results when running with this:

  # ipcs -b
  ipcs: invalid option -- b
  usage : ipcs -asmq -tclup
          ipcs [-s -m -q] -i id
          ipcs -h for help.
