This implementation leaves the door open for extending this helper past its obvious limitations, such as: test_cmp_cmd "some" "lines" -- test_cmp_cmd --stdin By using this in we'll catch cases where "git" or "test-tool" errors (such as segfaults or abort()) were previously hidden, and we'd either pass the test, or fail in some subsequent assertion.
