From 94b3b3746456949d834ec7bf454da3db4eb439cf Mon Sep 17 00:00:00 2001 From: Jeff King Date: Thu, 24 Feb 2011 09:29:50 -0500 Subject: [PATCH] trace: add trace_strbuf If you happen to have a strbuf, it is a little more readable and a little more efficient to be able to print it directly instead of jamming it through the trace_printf interface.
