Just to make sure we are on the same page, only "raw" format output is special and it is special only on output. Ancestry traversal always honors what you have in grafts.

However, you can do:

$ git rev-list --parents --pretty=raw

which would give you "commit $this_commit $its $parents" lines and "parent $true_parent" lines at the same time.

And they will be inconsistent when you have grafts or path limiter. The former honor grafts and path limiter, and the latter show the true set of parents.
