Add 1992/westley/try.sh + format fixes
The try.sh script runs the program for the world cities and the alt
version for the US cities, one at a time, that the author suggested, as
well as the approximate location that the entry was judged, noted from
the judges.
The README.md has been format fixed.
There is a possible bug in the alt version which is in the bugs.md file.
There is also a feature in the bugs.md which does introduce a strange
look in the README.md file:
STATUS: INABIAF - please **DO NOT** fix
STATUS: known bug - please help us fix
but they are for different things.

The author suggested that the alternate version, which Cody added (but fixed for
|

modern systems), should print

|
||||
...going down the left edge if your terminal auto-wraps at 80 characters.
|
||||
|
||||
This however does not seem to work. It does not appear to be because of the fix
|
||||
for modern systems as it doesn't work for gcc either, even before any changes.
|
||||
This might be a misunderstanding or it might be that having 80 columns (resized)
|
||||
does not count (though the output before the fix of the 80 column requirement
|
||||
showed was correct when at 80-columns so it seems like this could be a bug if
|
||||
not a misunderstanding).
