Subject: [PATCH v2 12/21] commit.c: report error on failure to fopen() the graft file

From: Nguyễn Thái Ngọc Duy <[email-masked]>
Date: Wed, 3 May 2017 17:16:57 +0700

Suppressing the error (because the command requires --quiet) is not a
concern because we already call error() just a couple lines down.
