merge_trees(): add ancestor label parameter for diff3-style output
Commands using the merge_trees() machinery will present conflict hunks in output something like what ‘diff3 -m’ produces if the merge.conflictstyle configuration option is set to diff3. The output lacks the name of the merge base on the ||||||| line of the output, and tools can misparse the conflict hunks without it. Add a new o->ancestor parameter to merge_trees() for use as a label for the ancestor in conflict hunks. If o->ancestor is NULL, the output format is as before. All callers pass NULL for now. If o->ancestor is non-NULL and both branches renamed the base file to the same name, that name is included in the conflict hunk labels. Even if o->ancestor is NULL I think this would be a good change, but this patch only does it in the non-NULL case to ensure the output format does not change where it might matter.
