Try to do for pydoc's GUI mode what the earlier checkin did for text

mode (identify the source class for class attrs; segregate attrs according
to source class, and whether class method, static method, property, plain
method, or data; display data attrs; display docstrings for data attrs
when possible).

Alas, this is mondo ugly, and I'm no HTML guy.  Part of the problem is
that pydoc's GUI mode has always been ugly under IE, largely because
<small> under IE renders docstrings unreadably small (while sometimes
non-docstring text is painfully large).  Another part is that these
segregated listings of attrs would *probably* look much better as bulleted
lists.  Alas, when I tried that, the bullets all ended up on lines by
themselves, before the method names; this is apparently because pydoc
(ab?)uses definition lists for format effects, and at least under IE
if a definition list is the first chunk of a list item, it gets rendered
on a line after the <li> bullet.

An HTML wizard would certainly be welcomed here.
