Junio C Hamano 73b063130b Merge branch 'tg/diff-no-index-refactor' ...

"git diff ../else/where/A ../else/where/B" when ../else/where is
clearly outside the repository, and "git diff --no-index A B", do
not have to look at the index at all, but we used to read the index
unconditionally.

* tg/diff-no-index-refactor:
  diff: avoid some nesting
  diff: add test for --no-index executed outside repo
  diff: don't read index when --no-index is given
  diff: move no-index detection to builtin/diff.c
