graph: don't try to get obsolete status for fake parent revisions Fake parents use negative revision numbers as internal placeholders. Previous Mercurial versions could handle negative non-existing revision numbers, but Mercurial 4.8 will fail on this invalid input when getting the obsolete status. Instead, make sure we only get obsolete status for actual revisions.
