ce_match_stat() calls into ce_compare_gitlink() for a 160000 entry,
which would resolve HEAD ref there and compares ce->oid with it.
But as you said, this is probably insufficient to emulate the
original. Shouldn't it call into run_diff_files(), which is the
in-core way to run the equivalent of "diff-files"?
