If you mean parsing "cat-file commit" output vs "rev-list
--parents" output, the former shows the true parents while the
latter shows a list of parents adjusted with information in the
grafts file.

If you are using pathspec then the latter further simplifies the
parent list, but you know that already and you are not using
that form here.
