[PATCH (pkgs)] Revert comint/shell changes

PATCH packages
This patch reverts work over the last year on upgrading comint and
shell. I'll continue working privately to try to get the problems
ironed out. In the meantime, everyone else can use the previous
version.
Note that I patched several other files in packages with respect to
their comint interfaces. Those other patches are still correct as they
update to the version of comint to which this patch reverts.
Hmmmm... due to a proxy server, I have to generate the diff on a
different machine from the one where I send email. Is there some way to
get patcher to handle a preexisting diff?
python-modes/ChangeLog addition:
2007-05-09 Jerry James <james at xemacs.org>
* pydoc.el (pydoc-kill-async-output): Revert the previous change
as part of reverting comint/shell.
xemacs-base/ChangeLog addition:
2007-05-09 Jerry James <james at xemacs.org>
* comint.el: Revert to pre-2006-05-16 version.
* shell.el: Ditto.
