 Did you notice that the body is empty?

 The best one can do to understand how the program works is to give it
 two small strings as arguments, and follow the program closely.  One
 could make the body of the 'while' loop an 'fprintf' with interesting
 variables like:
 
-    fprintf(stderr,
+
+	fprintf(stderr,
 	     "argv=%lo *argv=%lo **argv=%c argv[1]=%lo *argv[1]=%c argc=%d\n",

 	     (long) argv[1], argv[1] && *argv[1] ? *argv[1] : '@', argc);
 
+
 Furthermore, it's interesting to note that only two variables are
 used to achieve everything.
