This looks especially ugly for --oneline and other single-line formats. Looks very much like a bug. The code in question exists since commit 3969cf7db1. Probably the correct condition should be in fact "opt->output_format & DIFF_FORMAT_DIFFSTAT". Test t7007-show.sh is also modified to cover this case.
