Please describe the problem.

git-annex fsck tells ok, if there is no file present - is this behavior correct? I would expect git-annex to tell me that the file is not available. Well there is a (checksum...) ok output if the file exists, but I find 'ok' to be misleading if there is no file present. You could think that the file was checked and the checksum was correct - but this is not the case.

What steps will reproduce the problem?

Just drop/move a file in the repo and than fsck it. git-annex will tell you 'ok' but the file dosen't exits.

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)
