1# Test that go fix -diff exits with non-zero status when diffs exist,
2# and exits with zero status when no diffs are needed.
3# This is consistent with gofmt -d (#46289) and go mod tidy -diff (#27005).

5# When the source needs fixes, go fix -diff should print the diff
6# and exit with a non-zero code.
