   If we define our methods for stream-advance-to-column and stream-fresh-line,
   then stream-start-line-p, stream-terpri, stram-line-column are not invoked.
 
   Therefore we define another gray stream class. The first class is used
-  for all lower level functions (stream-terpri) and the second class
-  defines higher level functions (stream-fresh-line)
+  for all lower level functions (stream-terpri). The second class
+  is used to test methods for higher level functions (stream-fresh-line).
