I was surprised to see this as an addition to revision.c, and
only specific to limit_list() (and its iterative copy). I would
expect this to work for non-topo-order, too. I suppose we couldn't
completely trust that the first visit to a commit includes the
UNINTERESTING flag if there is clock skew in the commit history.
But could we also do this at the caller's end by passing a
callback that checks each walked commit if it is UNINTERESTING
and adds it to a set?
I know that the walking code in builtin/pack-objects.c does
this same computation, but it's muddled with other checks and
the trees are marked as UNINTERESTING at the same time. It
doesn't seem like we can reuse anything directly out of there,
but it did give me the idea to try a callback.
Thanks,
