    Use git rev-list --first-parent when checking out git repositories when CLEANDATE is set · 33bf76de

    This way we only check out a previous state of the requested branch.
    For example, if the history looks like:
    * (merge) commit 4
    | * commit 3
    | |
    | * commit 2
    * commit 1
    If a commit before 3 is requested, previously, commit 2 would be
    selected. With --first-parent, we only follow the left path, and commit
    1 is selected. This avoids checking out the intermediate state on a
    feature branch.
