### Please describe the problem.

Selectively auditing the files annexed on an S3 container, where the file is stored by keyname, I attempted to confirm that the file is also annexed locally.

When I run git-annex whereused --key <keyname>, nothing comes up. But if I look for the file locally, I can see that it exists.

If I add --historical, I can see the file exists in some previous commit that I thought had been successfully merged, and moved on from. It seems like this might be related to export trees, because that keyword is also present in the output with --historical

My reading of the documentation is that the file being present in the local annex shouldn't require the --historical argument, which is much slower.
