Update 1993 winning entries' README.md files

Format and typo fixes. Starting with this year I actually did more
thorough typo fixes. It might be that I did some of this in earlier
years too but I am sure I did it for this year and beyond (at least up
through 1995 .. not sure about years beyond that that I have also
edited). Even so I'll probably want to do another pass through all files
before I can say that the typo issue is resolved. That includes possibly
other files and the worst of all files in my entries.

 intentional spelling error there.

 ## Judges' remarks:
 
 After this program prints the contents of 'file', ask it
 some questions related to the text.
