What does the following mean? I would expect that if we encounter a duplicate while using the --deduplicate option, the duplicate file would be removed from the import location and import would continue. Does that mean that the newly encountered img_0405.jpg is different from the one previously seen? Could the error message perhaps be improved?

.../usbdisk/annex(master)$ git annex import --deduplicate ../Pictures/
import Pictures/2008/10/12/img_0405.jpg git-annex: not overwriting existing Pictures/2008/10/12/img_0405.jpg (use --force to override)

Many other duplicates are being tidied away.
