What did you expect to happen? (Expected behavior) The first "git diff-index" should not detect any differences, but return 0 instead.
What happened instead? (Actual behavior) The first "git diff-index" considers the touched README.md as dirty and returns 1. Somehow, calling "git status" fixes this behaviour so that the second "git diff-index" behaves as expected.
What's different between what you expected and what actually happened? The result of the first "git diff-index" should have been 0. And the behaviour should not alter at all with calling any other git commands like "git status" or "git diff" in between.
Anything else you want to add: The same issue holds true for "git diff-files".
