ll_merge(): add ancestor label parameter for diff3-style output
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.
