### Please describe the problem.

Calling `git annex import --force file-in-working-copy` removes `file-in-working-copy` from disk.

My workflow is:

1) copy the CR2 files from a card to the desired directory structure using a tool of my choice,
2) import the created directory layout to git-annex

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

[[!format sh """
$ git-annex version
