257 revision for testing. Once you have performed tests, mark the 257 revision for testing. Once you have performed tests, mark the
258 working directory as bad or good and bisect will either update to 258 working directory as bad or good and bisect will either update to
259 another candidate changeset or announce that it has found the bad 259 another candidate changeset or announce that it has found the bad
