Re: Prevent reset --hard from deleting everything if one doesn't have any commits yet

Wouldn't that mean all of the file data is available in the object
database? Unfortunately without an index, there's nothing to mark which
file was which. But `git fsck --lost-found` should copy out all of the
file content into .git/lost-found.

If we had a hierachically stored index that stores subdirectory
contents as a tree (or some tree-like things), "fsck --lost-found"
would have been able to recover even pathnames, but with the current
flat index in a fresh directory without any commit, we'd get bunch
of blobs without any clue as to where each of them goes.  It would
be far better than nothing, but leaves room for improvement.
