broken link - what is it?

I seem to have a corrupted repo:

man git-fsck does not document what "broken link" is. Can someone enlighten me please?

Hi,

On Tue, 24 Jul 2007, Michael S. Tsirkin wrote:

A broken link is when an object references another object, and the latter was not found in the object database.

For example, commits reference parent commits and a tree. A tree references trees and blobs. A tag references arbitrary objects.

I am not very good in writing documentation... could you give it a try?

Thanks, Dscho
