Oh, so --index requires the index and worktree to match and the worktree 
cannot represent i-t-a so they don't match. I'm still not totally 
convinced that it is useful to prevent a creation patch from applying 
when the path is missing from the worktree but is marked as i-t-a in the 
index but I guess it matches the behavior the general behavior where a 
patch can be successfully applied with 'apply' and 'apply --cached' but 
not with 'apply --index'

Thanks for clarifying that
