From f44213258de3fbef932f9c655213202f69dccc80 Mon Sep 17 00:00:00 2001 From: Tommi Kyntola Date: Fri, 16 Feb 2007 10:50:58 +0200 Subject: [PATCH] git-blame: prevent argument parsing segfault The 3rd branch in builtin-blame.c should also check for lacking arguments. Running that in top dir does not trigger the problem because the 'prefix' is NULL.
