Describe the bug

I have an assertion failing: mail_selected is not in mail_copied, mail_moved, mail_deleted.

Mails	Metric
Rejected	1
Discarded	1073
Selected	1074
Deleted	1073

Duplicate sets	Metric
Skipped - Content	1
Deduplicated	1073

To reproduce

$ mdedup mail/* mail2/* -s discard-matching-path -r "^/home/user/mail2/*" -a delete-discarded -n

Expected behavior

I'm guessing this is a simple case of subtracting rejected or skipped from selected, but if you actually do need a lot more data to debug this, let me know.

With all your PRs merged upstream, does the problem persist? In which case feel free to submit a new PR with your suggestion of "subtracting rejected or skipped from selected". Best case would be to have a unittest accompanying this fix, but I'm ready to merge it as-is if it doesn't break any.

I'm pretty sure it does, yeah. I've been mostly playing around with deduplicating between two dirs and using the -r option and I almost always get some kind of statistics mismatch error on a sufficiently large and complex email base.
