Subject: ipcs: reorganize help and usage texts

Help text old version:

	ipcs provides information on ipc facilities for which you have read access.
	Resource Specification:
		-m : shared_mem
		-q : messages
		-s : semaphores
		-a : all (default)
	Output Format:
		-t : time
		-p : pid
		-c : creator
		-l : limits
		-u : summary
	-i id [-s -q -m] : details on resource identified by id
	usage : ipcs -asmq -tclup
		ipcs [-s -m -q] -i id
		ipcs -h for help.

New version:
	Usage: ipcs [resource]... [output-format]
	       ipcs [resource] -i id

	Provide information on IPC facilities for which you have read access.

	    -h      display this help
	    -i id   print details on resource identified by id

	Resource options:
	    -m      shared memory segments
	    -q      message queues
	    -s      semaphores
	    -a      all (default)

	Output format:
	    -t      time
	    -p      pid
	    -c      creator
	    -l      limits
	    -u      summary

Usage text old version:
	usage : ipcs -asmq -tclup
		ipcs [-s -m -q] -i id
		ipcs -h for help.

New version:
	Usage: ipcs [-asmq] [-t|-c|-l|-u|-p]
	       ipcs [-s|-m|-q] -i id
	       ipcs -h for help

[kzak@redhat.com: - use program_invocation_short_name
                  - minor cleanups]
