From: Elijah Newren <newren@xxxxxxxxx>
In commit 0c4fd732f0 ("Move computation of dir_rename_count from
merge-ort to diffcore-rename", 2021-02-27), much of the logic for
computing directory renames moved into diffcore-rename.
directory-rename-detection.txt had claims that all of that logic was
found in merge-recursive. Update the documentation.
