From f1f8ca7ddc1dfb84293ea10f0621a65ab161944c Mon Sep 17 00:00:00 2001
From: Jim Meyering <jim@meyering.net>
Date: Fri, 21 Feb 2003 07:47:06 +0000
Subject: (apparent_size): New global. (print_only_size): Reflect the fact that
 we're printing byte counts, not ST_NBLOCKSIZE-byte-block counts.
 (print_size): Call print_only_size rather than duplicating its code.
 (process_file): Accumulate byte counts, rather than block counts.
