I haven't looked at the implementation, so this may be an entirely
stupid suggestion, but would it be possible to instead render the
completions as?

    % git checkout --<tab>
    --[no-]conflict=                   --[no-]patch
    --[no-]detach                      --[no-]progress
    --[no-]ignore-other-worktrees      --[no-]quiet
    --[no-]ignore-skip-worktree-bits   --[no-]recurse-submodules
    --[no-]merge                       --theirs
    --[no-]orphan=                     --[no-]track
    --ours

This would address the problem of the --no-* options taking double the
screen space.

It's also more intuitive than that lone and somewhat weird-looking
"--no-" suggestion.
