Ick.
Interestingly, the new paths I added for additional output are not
being triggered here. Rather, "normal" renames are being considered
unprocessed (I had a faulty assumption in the previous patch that a
clean merge would have cleared out the higher stage entries in
dst_entry as a side effect). Because of this, normal renames are
needlessly re-processed in process_entry(), and trigger extra output
as a side-effect. One could work around this by the following patch,
though it'd be better to just avoid the extra reprocessing. I'll
submit a better patch in a minute.
