/*
* Purpose of src_entry and dst_entry:
*
* If 'before' is renamed to 'after' then src_entry will contain
* the versions of 'before' from the merge_base, HEAD, and MERGE in
* stages 1, 2, and 3; dst_entry will contain the respective
* versions of 'after' in corresponding locations. Thus, we have a
* total of six modes and oids, though some will be null. (Stage 0
* is ignored; we're interested in handling conflicts.)
*
* Since we don't turn on break-rewrites by default, neither
* src_entry nor dst_entry can have all three of their stages have
* non-null oids, meaning at most four of the six will be non-null.
* Also, since this is a rename, both src_entry and dst_entry will
* have at least one non-null oid, meaning at least two will be
* non-null. Of the six oids, a typical rename will have three be
* non-null. Only two implies a rename/delete, and four implies a
* rename/add.
