From 6f6f3fcb87a53c720941f4bd039ec2c0bce66625 Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Thu, 12 Feb 2015 15:02:24 -0800 Subject: hexdump: fix ascii column for the tail of a dump In the current implementation we have a floating ascii column in the tail of the dump. For example, for row size equal to 16 the ascii column as in following table group size \ length 8 12 16 1 50 50 50 2 22 32 42 4 20 29 38 8 19 - 36 This patch makes it the same independently of amount of bytes dumped. The change is safe since all current users, which use ASCII part of the dump, rely on the group size equal to 1. The patch doesn't change behaviour for such group size (see the table above).
