From 0ec29a4760e7c1dd1e168f6dbdd22b87559a26e9 Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Sat, 28 Jul 2007 17:17:17 -0700 Subject: [PATCH] log_ref_write() -- do not chomp reflog message at the first LF A reflog file is organized as one-line-per-entry records, and we enforced the file format integrity by chomping the given message at the first LF. This changes it to convert them to SP, which is more in line with the --pretty=oneline format.
