When blaming files, changes in the work tree are taken into account
and displayed as being "Not Committed Yet".
However, when blaming a file that is not known to the current HEAD,
git blame fails with `no such path 'foo' in HEAD`, even when the file
was git add'ed.
This would seem uninteresting with the plain `git blame` case, which
it is, but it becomes useful when using copy detection, and the new file
was created from pieces already in HEAD, moved or copied from other
files.
