Yes, the conflicted case cannot sanely be handled _without_ leaving higher stage entries in the index, and that is exactly why I made it incompatible with the "--cached" mode. It might be OK to only allow the combination when everything auto resolves cleanly and fail the operation without touching either the index or the working tree. Pretending there was no delete/modify conflicts or adding contents with unresolved conflicts as if nothing bad happened as stage 0 entries would never be acceptable. Perhaps * Error out if the index does not match HEAD. * Try applying to the contents in the index. If there are any structural conflicts, leave these paths at higher stage and do not touch their contents. * For paths without structural conflict but need content merges, attempt ll-merge of the contents. If autoresolves cleanly, register the result at stage 0. Otherwise, discard the failed conflicted merge, and leave stages 1, 2 and 3 as they are. * Exit with status 0 if and only if everything has resolved cleanly. Otherwise, exit with non-zero status. would be the minimally-acceptably-safe behaviour.
