"git diff" does not record index lines for pure mode changes (i.e. no lines changed). Therefore, apply --index-info would call out a bogus error. Instead, fall back to reading the info from the current index. Incidentally, this fixes an error where git-rebase would not rebase a commit including a pure mode change, and changes requiring a threeway merge. Noticed and later tested by Chris Shoemaker.
