qemu-img info should only be used directly if the format-specific information or the name of the format is relevant (some tests explicitly test format-specific information; test 082 uses qcow2-specific settings to test the qemu-img interface); otherwise, tests should always use _img_info instead. Test 082 was touched only partially. It does test the qemu-img interface; however, its invocations of qemu-img info are not real tests but rather verifications, so if format-specific information is not important for the test, there is no reason not to use _img_info. In contrast to directly invoking qemu-img info, "qcow2" is replaced by "IMGFMT"; but as "qcow2" is only mentioned once in test 082 (in _supported_fmt), I consider this an improvement.
