Stress test the usage emitted when options are combined in ways that isn't supported. Let's test various option combinations, some of these we buggily allow right now. E.g. this reveals a bug in 321459439e1 (cat-file: support --textconv/--filters in batch mode, 2016-09-09) that we'll fix in a subsequent commit. We're supposed to be emitting a relevant message when --batch-all-objects is combined with --textconv or --filters, but we don't. The cases of needing to assign to opt=2 in the "opt" loop are because on those we do the right thing already, in subsequent commits the "test_expect_failure" cases will be fixed, and the for-loops unified.
