OK - given this reasoning I agree that --fork-point makes sense.

I think this would have been clearer if the short description said
something like:

    Find the point at which a branch forked from another branch; this
    does not just look for the common ancestor of the two commits but
    also takes into account the reflog of <ref> to see if the branch
    forked from an earlier incarnation.
