git annex fsck currently spams the terminal with all keys in a repo and prints git-annex: fsck: n failed at the end if errors occur. Finding these errors in a sea of oks is not trivial however.

A simple solution to this could be an fsck option which skips printing ok'd (and perhaps also dead) keys, i.e. --no-ok and --no-dead.
