From bf975d379d79ab0eb9e8835af4abab4712e71dad Mon Sep 17 00:00:00 2001 From: Jonathan Nieder Date: Sat, 20 Mar 2010 19:46:07 -0500 Subject: [PATCH] cherry-pick, revert: add a label for ancestor MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit When writing conflict hunks in ‘diff3 -m’ format, also add a label to the common ancestor. Especially in a cherry-pick, it is not immediately obvious without such a label what the common ancestor represents. git rerere does not have trouble parsing the new output and its preimage ids are unchanged since it includes its own code for recreating conflict hunks. No other code in git parses conflict hunks.
