It is possible that the conflict left when making the same merge are
actually different when using these two conflict styles. IOW, if
the merge produces
<<<
side A
|||
common
===
side B
>>>
when diff3 style is chosen, but if the same merge results in
<<<
side A'
===
side B'
>>>
where side A' is not identical to side A (or B' and B are not
identical), then we will fail to find the previously recorded
resolution.
