Sorry, I was thinking of something else when I closed this.  What you want is a new -x option, for some 'x'.  The following would help, especially as there is no one who specifically maintains pydoc.

a) a specific proposal or set of proposals as to what letter to use for the option and what the result should be.

b) a currently failing test case (based on the above).

c. a patch for test.test_pydoc adding the test, preferably self-contained (no added file)  -- or does any current test already involve an 'at 0xnnnnnnnn' output?

d. a patch for  pydoc.py making the test pass.
