Subject: SF bug #501591:  dir() doc is old Bugfix candidate.

+ Updated dir() description to match actual 2.2 behavior.

+ Replaced the dir(sys) example with dir(struct), because the former
  was way out of date and is bound to change frequently, while the
  latter is stable.

+ Added a note cautioning that dir() is supplied primarily for
  convenience at an interactive prompt (hoping to discourage its
  use as the foundation of introspective code outside the core).

   Without arguments, return the list of names in the current local

-  attribute for that object.  This information is gleaned from the
+  attributes for that object.  This information is gleaned from the
   object's \member{__dict__} attribute, if defined, and from the class

-  example, for classes, attributes defined in base classes are not
-  included, and for class instances, methods are not included.
-  The resulting list is sorted alphabetically.  For example:
+  or type object.  The list is not necessarily complete.

+  If the object is a type or class object,
+  the list contains the names of its attributes,

+  Otherwise, the list contains the object's attributes' names,
+  the names of its class's attributes,
+  and recursively of the attributes of its class's base classes.
+  The resulting list is sorted alphabetically.
+  For example:
 
 \begin{verbatim}
->>> import sys
+>>> import struct
 >>> dir()
-['sys']
->>> dir(sys)
-['argv', 'exit', 'modules', 'path', 'stderr', 'stdin', 'stdout']
