That's not the point.
If somebody does a "git rebase", he might be changing the heads that have
already been packed, and replacing them them with heads that have _not_
yet been packed. So the _dangling_ links are the old ones (in the
pack-file), and "git-fsck-objects --full" is needed to see them.
That said, I still don't think Alan sees what he says he sees. Even if
something crashes in the middle of a "git rebase", I think the old head
should have been saved in .git/ORIG_HEAD, for example.
That said, some of the more invasive operations (and "git rebase"
certainly counts) should probably have a few "sync" operations to make
sure that things like ORIG_HEAD really are on disk, so that we would be
able to recreate the tree even _without_ anything like "git-fsck-objects".
