Could you please try

import readline

and paste in the output?

With GNU readline, we get:

In [2]: readline.
readline.__builtins__                readline.get_current_history_length
readline.__class__                   readline.get_endidx
readline.__delattr__                 readline.get_history_item
readline.__dict__                    readline.get_history_length
readline.__doc__                     readline.get_line_buffer
readline.__file__                    readline.have_readline
readline.__getattribute__            readline.insert_text
readline.__hash__                    readline.parse_and_bind
readline.__init__                    readline.read_history_file
readline.__name__                    readline.read_init_file
readline.__new__                     readline.redisplay
readline.__reduce__                  readline.remove_history_item
readline.__reduce_ex__               readline.replace_history_item
readline.__repr__                    readline.set_completer
readline.__setattr__                 readline.set_completer_delims
readline.__str__                     readline.set_history_length
readline._rl                         readline.set_pre_input_hook
readline.add_history                 readline.set_startup_hook
readline.clear_history               readline.sys
readline.get_begidx                  readline.uses_libedit
readline.get_completer               readline.write_history_file

And the critical one is


which we use to rewrite the new line you're about to type into via the
pre_readline method:


If that function doesn't exist, or is a no-op, we're stuck without
auto-indent in Leopard.  If it does work, then we may be doing
something else incorrectly though.  I unfortunately don't have a
leopard box to test on yet (waiting for my wife's laptop to
