 Style conventions for stub files are different from PEP 8. The general
 rule is that they should be as concise as possible.  Specifically:
-* there is no line length limit;
-* prefer long lines over elaborate indentation;
+* lines can be up to 130 characters long;
 * all function bodies should be empty;
 * prefer ``...`` over ``pass``;
 * prefer ``...`` on the same line as the class/function signature;
