List possible executables for output paging

The UNIX systems often come with “pg” and “more” but no “less” utility. The Linux usually provides “less” and “more” pager, but often no “pg”. MacOS comes with “less” and “more” pager and no “pg”. Windows provides “more”. The “more” pager is the oldest utility and thus most compatible with many systems.
