OK, thanks. I think my algorithm will change to be this:

1. For all images in index.xml that have exact md5/path matches in my
   shadow.db3, mark as processed.
2. For all remaining images in index.xml that have a single partial
   match (just path or just md5) in shadow.db3, accept and mark as moved
   or edited. If multiple partial matches, either exit program or ask
   user to disambiguate.
3. For all remaining images in index.xml that have no match, accept as
4. Delete all images in shadow.db3 that did not have any match in

Previously I was able to do a single sweep through index.xml --
allowing duplicates requires a preliminary sweep.
