p4211 tests line-log performance both with and without "-M". In v2.9.0, the case without "-M" appears to have regressed badly, but that is only because we flipped on renames by default. Let's have the test explicitly disable renames to get consistent timings (and to match the presumed intent of the test, which is to see the effects with and without renames).
