From f01de62e4591a6acc061eb994d44f7eeef7a0cfd Mon Sep 17 00:00:00 2001 From: Jonathan Nieder Date: Sat, 20 Mar 2010 19:38:58 -0500 Subject: [PATCH] ll_merge(): add ancestor label parameter for diff3-style output MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Commands using the ll_merge() function will present conflict hunks imitating ‘diff3 -m’ output if the merge.conflictstyle configuration option is set appropriately. Unlike ‘diff3 -m’, the output does not include a label for the merge base on the ||||||| line of the output, and some tools misparse the conflict hunks without that. Add a new ancestor_label parameter to ll_merge() to give callers the power to rectify this situation. If ancestor_label is NULL, the output format is unchanged. All callers pass NULL for now.
