    t3510: stop using '-m 1' to force failure mid-sequence of cherry-picks
    
    We are going to allow 'git cherry-pick -m 1' for non-merge commits, so
    this method to force failure will stop to work.
    
    Use '-m 4' instead as it's very unlikely we will ever have such an
    octopus in this test setup.
