+With `--wrap=none`, `QuitSmall` only checks whether the content fits vertically. When the current screen is written on exit (`IsWriteOriginal: false`, the default), lines wider than the screen are truncated. If you want `ov` to stay open whenever no-wrap content extends beyond the screen width, set `QuitSmallNoTruncate` to `true`.

+```yaml

+`QuitSmallNoTruncate` has no effect when `IsWriteOriginal: true`, because the original lines are written in full regardless of the screen width.
