Cool! Testing on Linux repo:

Without it:

    $ time git log --oneline --graph | head -1
    *   0d3eb744aed4 Merge tag 'urgent-rcu.2023.04.07a' of git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu

    real	0m11.379s
    user	0m10.655s
    sys	0m0.726s

With it:

    $ time git log --oneline --graph | head -1
    *   0d3eb744aed4 Merge tag 'urgent-rcu.2023.04.07a' of git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu

    real	0m0.032s
    user	0m0.014s
    sys	0m0.023s

Maybe I’m gonna enable `git maintenance` for my repos. :)
