### Please describe the problem.

    git annex fsck --from $remote

copies the symlinks from the remote into *.git/annex/tmp*, which then fail to fsck as they don't point to content.

In the transcript below, the 'a' file should fail fsck, but the rest pass.

### What steps will reproduce the problem?

See transcript

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

* git-annex version: 5.20150409-g3575ee5
* Arch Linux (git-annex-bin)
