From b4833a2c62578bdbfd300e296702214cb1b9a601 Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Wed, 26 Sep 2007 23:34:01 -0700 Subject: [PATCH] rerere: Fix use of an empty strbuf.buf The code incorrectly assumed that strbuf.buf is always an allocated piece of memory that has NUL at offset strbuf.len. That assumption does not hold for a freshly initialized empty strbuf.
