Summary: dict.update should take a 2-tuple sequence like dict.__init_

Initial Comment:
This patch allows:
    d = {}
    d.update([(1,2), (3,4)])

The current way to do it is (unfortunately):
    d = {}
    d.update(dict([(1,2), (3,4)]))

The (__doc__) documentation doesn't cover that case.. it says "new..." 
for every signature of dict.__init__.

Attempting to call __init__ multiple times isn't really an obvious thing to 
do, because it almost never does what you want.  I would chalk that up 
to an implementation detail of dict, not intended behavior :)

Though not exactly obvious, this functionality and more is
available through dict.__init__().

Since it would be a change to an important API, referring to
Guido for pronouncement.  My vote is -0.
