------------------------------------------------------
From: Andy Shevchenko <andriy.shevchenko@xxxxxxxxxxxxxxx>
Subject: test_hexdump: test all possible group sizes for overflow
Currently the only one combination is tested for overflow, i.e. rowsize =
16, groupsize = 1, len = 1. Do various test to go through all possible
branches.
