Subject: [PATCH] blkid: remove -w option from man page and usage() output

The option does not have any effect, the original functionality was
removed from e2fsprogs in year 2003 by

 commit	50b380b4d4ab668bad45033e3a8aaf93c7f42844
 git://git.kernel.org/pub/scm/fs/ext2/e2fsprogs.git

So.. don't propagate the option to users in year 2012 :-)
