merge-recursive: track information associated with directory renames
Directory rename detection previously silently applied. In order to
allow printing information about paths that changed or printing a
conflict notification (and only doing so near other potential conflict
messages associated with the paths), save this information inside the
rename struct for later use. A subsequent patch will make use of the
additional information.
