feat(column)!: rework 'statuscolumn' %r/l items

Problem:  A custom 'statuscolumn' needs to check a bunch of options and
          placed signs to replicate the default number column.
Solution: Rework %l item to include the necessary logic to mimic the
          default number column. Remove now redundant %r item.
