… the MAX_WIDTH setting


Fixes ewels#109

- Fix ewels#109 by changing the behavior of MAX_WIDTH to still use the full width of the
  terminal if it is less than the limit
- Add new flag WIDTH to take over the previous functionality of
  MAX_WIDTH
- Adopt test expectations to new and modified configuration flags
- Add new test for MAX_WIDTH
