From d0d2344ad84cde7fddedc1e141296607af673454 Mon Sep 17 00:00:00 2001 From: Tobias Klauser Date: Thu, 14 Jan 2016 17:57:54 +0100 Subject: [PATCH] trailer: allow to write to files other than stdout Use fprintf instead of printf in trailer.c in order to allow printing to a file other than stdout. This will be needed to support in-place editing in git interpret-trailers.
