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
