git-diff.txt: document return code of `--no-index`
Within diff_no_index(), we have the following: revs->diffopt.flags.exit_with_status = 1; ... /* * The return code for --no-index imitates diff(1): * 0 = no changes, 1 = changes, else error */ return diff_result_code(&revs->diffopt, 0); Which means when `git diff` is run in `--no-index` mode, `--exit-code` is implied. However, the documentation for this is missing in git-diff.txt. Add a note about how `--exit-code` is implied in the `--no-index` documentation to cover this documentation blindspot.
