Please describe the problem.

1. Some files remain symlinked after aborted git annex add and completed git annex unannex
2. This files are present in`.git/annex/objects but git annex unused does not find them. Running git annex whereused --key=SHA256E... runs empty.

To restore files and remove them from git-annex objects folder - need manual workarounds or hacks like adding file again with git annex add and trying to removing it again

What steps will reproduce the problem?

1. run git annex add and abort operation mid-way (this was on directory with large number of files ~3K and running with 12 jobs command switch)
2. run git annex unannex until done
3. find that some files that were added - were restored, and some still symlinked but are not tracked by git annex

What version of git-annex are you using? On what operating system?

Have you had any luck using git-annex before? (Sometimes we get tired of reading bug reports all day and a lil' positive end note does wonders)

Yes, using it extensively for a few years with terabytes of data
