    git-arc: allow word splitting in build_commit_list()
    
    git-rev-list expects commits to be listed separately, allow word
    splitting and disable shellcheck SC2086 when using git-rev-list
    to build the commit list.
    
    Fixes: 4fd0c6ab1a9e ("Fix most shellcheck warnings in git-arc.sh")
