Add alt code to 1988/westley

The reason is it seems instructional and entertaining to see what
happens if the problem that the judges described in their remarks
occurs. Now one can do make clobber all alt; ./westley.alt; ./westley
and see if they are the same output.

The .gitignore file was updated - added westley.alt.

Updated README.md not only referring to the alt code but also format
fixes (the original fix of this commit).

+## To build:
+
+```sh
+make all
+```
+
+Misha Dynin provided a fix for [westley.c](westley.c) so that it may compile on 
+both K&R and more modern C compilers. Thank you Misha! The original code, used
+for entertainment and educational value, is in [westley.alt.c](westley.alt.c),
+described below.
 
 ## Try:
 
-	make all
-	./westley
+```sh
+./westley
+```

-## Judges' remarks
+## Judges' remarks:
 
 Your compiler must parse
 
-		#define _ -a
-		-_
+```c
+#define _ -a
+-_
+```
 
-as "--a" and not "-(-a)" or some other tokenized form.  Some strictly
+as `--a` and not `-(-a)` or some other tokenized form.  Some strictly
 conforming ANSI C Preprocessors may object to this: for such
 compilers, you can elide the non-standard token-pasting requirement
 by changing the #define line to:
 
-		#define _ F-->00||F-OO--;
+```c
+#define _ F-->00||F-OO--;
+```
 
 You might enjoy looking at the output of:
 
-	cc -E westley.c
+```sh
+cc -E westley.c
+```
+
+### Alternate code:
+
+To see if your compiler has the problem described above try:
+
+```sh
+make alt
+./westley.alt
+```
+
+Does it show the same output as `westley`?
