Minor updates to 1991/fine

I updated the try.sh with a new string that I discovered that is for fun
output especially given something the judges say in the guidelines.

Also since some of the strings are from Brian Westley's entry from 1989
and another one was credited to him I briefly referred to the entry as
well.

 Make sure that you read the last line backwards! Credit goes to [Merlyn LeRoy (Brian
 Westley)](/winners.html#Brian_Westley) for that. See his 22 August 1992

+Some others come from his 1989 entry as well. To
 those who have a harder time reading backwards it says: `Gary lent the rug`,
 rotated from `the rug gary lent`!
