Re: [PATCH 3/5] rebase: factor out merge_base calculation

>>>   -	merge_bases = get_merge_bases(onto, head);
>>> -	if (!merge_bases || merge_bases->next) {
>>> -		oidcpy(merge_base, null_oid());
>>> +	if (is_null_oid(merge_base))
>>>   		goto done;
>>> -	}
>>>   -	oidcpy(merge_base, &merge_bases->item->object.oid);
>>>   	if (!oideq(merge_base, &onto->object.oid))
>>>   		goto done;
>> Looking at the change in "git show -W", it seems that this function
>> no longer touches merge_bases at all, other than initializing it to
