I keep the -M option. I think it is more clear if "ipcs -m" outputs only 
one line for each shared memory and it gets more similarity with "ipcs 
-s" and "ipcs -q". Actually, there are a lot of information about shared 
memory like below.

[root at localhost ipcs]# ipcs -i 0 -m

Shared memory Segment shmid=0
uid=0   gid=0   cuid=0  cgid=0
mode=0666       access_perms=0666
bytes=90000     lpid=30412      cpid=30412      nattch=0
att_time=Thu Apr 19 10:55:34 2012
det_time=Fri Apr 20 11:39:06 2012
change_time=Thu Apr 19 10:55:34 2012

Maybe later, we will need not only PAGES and VFS_INODE. We may need some 
information about time. So keeping -M option is necessary.

P.S.
the two useless item has been removed, please refer to the attachment.
