 The basic use case uses the default ASCII lexer to split a string into sub-strings:
 
-	shlex.Split("one \"two three\" four") -> []string{"one", "two three", "four"}
+  shlex.Split("one \"two three\" four") -> []string{"one", "two three", "four"}
 
 To process a stream of strings:
 
-	l := NewLexer(os.Stdin)
-	for ; token, err := l.Next(); err != nil {
-		// process token
-	}
+  l := NewLexer(os.Stdin)
+  for ; token, err := l.Next(); err != nil {
+  	// process token
+  }
 
 To access the raw token stream (which includes tokens for comments):
 
-	  t := NewTokenizer(os.Stdin)
-	  for ; token, err := t.Next(); err != nil {
-		// process token
-	  }
+  t := NewTokenizer(os.Stdin)
+  for ; token, err := t.Next(); err != nil {
+	// process token
+  }
