small feature request w/ patch

[Ryan Davis]

I'm trying to organize my workplace lisp libraries (from a cobble of
source checkouts and asdf-installed stuff), and we had a small patch to
iterate that I'd like in the mainline so we can consume iterate via
quicklisp.

It adds a new restart in #'ambiguity-check-clause to delete one of the
clauses to resolve the ambiguity. This has been very helpful when
developing and debugging new iterate drivers, and I don't think it has
any other relevant effects.

Attached is a dpatch created with `darcs send -O`, but if that doesn't
work here's the diff:

diff -rN old-iterate/iterate.lisp new-iterate/iterate.lisp
1322c1322,1323
< (error "Iterate: Inserting clause ~a would create ~
---

(restart-case
(error "Iterate: Inserting clause ~a would create ~

1324c1325,1328
< kw1 kw2))))
---

kw1 kw2)
(delete-conflict ()
:report "Delete the original clause"
(remove-clause kw2))))))

Thanks,
