Hmph, even when we are not doing the mark-tags-complete thing,
wouldn't it be a fatal error if the commit graph claims a commit
exists but we are missing it?
It also makes me wonder if it would be sufficient to prevent us from
saying "have X" if we just pretend as if lookup_commit_in_graph()
returned NULL in this case.
In any case, infinitely recursing to lazily fetch a single commit is
definitely worth fixing. Thanks for digging to the bottom of the
problem and fixing it.
