[PATCH 04/11] merge-ort: have ll_merge() calls use the attr_index for renormalization

["Elijah Newren via GitGitGadget" <gitgitgadget@gmail.com>]

From: Elijah Newren <newren@gmail.com>

ll_merge() needs an index when renormalization is requested.  Give it
the special one we created exactly for that purpose.  This fixes t6418.4
and t6418.5 under GIT_TEST_MERGE_ALGORITHM=ort.
