From 6ccd3b91c18d8b13bc468ef962a9ef9dfc6c4515 Mon Sep 17 00:00:00 2001
From: Mike Frysinger <vapier@gentoo.org>
Date: Sat, 14 Aug 2010 01:16:42 -0400
Subject: [PATCH] tracepath: re-use printf return in print_host
The printf funcs take an int for field widths, not a size_t. Also, since
the printf funcs already return the length of chars displayed, use that
value instead of re-calculating the length with strlen.
