patch 9.1.2126: vim --version used single column for feature list

Problem:  vim --version used single column for feature list
          (Ben Knoble, after v9.1.1898)
Solution: Restore old behaviour and assume 80 columns, making sure
          the feature list is shown in several columns
          (Ben Knoble, Hirohito Higashi).

fixes:  #19309
closes: #19315
