Built a `git-recover-repository` command today. So far it only does the
detection and deletion of corrupt objects, and retrieves them from remotes
when possible. No handling yet of missing objects that cannot be recovered
from remotes.
Here's a couple of sample runs where I do bad things to the git
repository and it fixes them:
<pre>
joey@darkstar:~/tmp/git-annex>chmod 644 .git/objects/pack/*
joey@darkstar:~/tmp/git-annex>echo > .git/objects/pack/pack-a1a770c1569ac6e2746f85573adc59477b96ebc5.pack
joey@darkstar:~/tmp/git-annex>~/src/git-annex/git-recover-repository
Running git fsck ...
git fsck found a problem but no specific broken objects. Perhaps a corrupt pack file? Unpacking all pack files.
fatal: early EOF
Unpacking objects: 100% (148/148), done.

Re-running git fsck to see if it finds more problems.

Successfully recovered repository!
You should run "git fsck" to make sure, but it looks like
everything was recovered ok.
</pre>

Works great! I need to move this and `git-union-merge` out of the git-annex
source tree sometime.
