From 967dfd4d568c2b102281de8cc22ee35f7558358b Mon Sep 17 00:00:00 2001 From: Jonathan Tan Date: Wed, 2 Nov 2016 10:29:20 -0700 Subject: [PATCH] sequencer: use trailer's trailer layout Make sequencer use trailer.c's trailer layout definition, as opposed to parsing the footer by itself. This makes "commit -s", "cherry-pick -x", and "format-patch --signoff" consistent with trailer, allowing non-trailer lines and multiple-line trailers in trailer blocks under certain conditions, and therefore suppressing the extra newline in those cases. Consistency with trailer extends to respecting trailer configs. Tests have been included to show that.
