[PATCH v4 09/10] merge-ort: mark conflict/warning messages from inner merges as omittable

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

From: Elijah Newren <newren@gmail.com>

A recursive merge involves merging the merge bases of the two branches
being merged.  Such an inner merge can itself generate conflict notices.
While such notices may be useful when initially trying to create a
merge, they seem to just be noise when investigating merges later with
--remerge-diff.  (Especially when both sides of the outer merge resolved
the conflict the same way leading to no overall conflict.)  Remove them.
