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.
