However, '-u' indiscriminately adds all modified tracked paths, including unmerged paths that may still contain unresolved conflict markers. It also adds tracked files modified in the worktree that are not involved in the ongoing merge. The latter is not a huge problem for "git rebase", which refuses to start with any local changes, but is a problem for "git merge", which is often run with local changes in maintainer workflows. Introduce 'git add --resolved' to add only unmerged paths, limited by an optional pathspec, where no conflict markers remain in the working tree. Before modifying the index, scan unmerged regular files for leftover conflict markers using a new helper, has_conflict_markers(), defined in merge-ll.c in terms of the is_conflict_marker_line() helper we introduced earlier. If any unmerged path still contains conflict markers, show an error listing the conflicted paths and abort without updating the index. Otherwise, add these unmerged paths that do not have conflict markers to the index. Note that unmerged paths without conflict markers (such as binary files and deletions) are added as resolved using add_file_to_index() and remove_file_from_index_with_flags(). Tracked files that were not in a conflicted state are ignored by '--resolved'.
