Summary: globaling a variable twice issues warn

Initial Comment:
The following code generates a warning:

def foo():
    global dammit
    dammit = 5
    global dammit

test.py:1: SyntaxWarning: name 'dammit' is assigned to
before global declaration  def foo():

One would argue that this should still issue a warning,
but the warning it raises is a bit confusing
(especially when the two global statements are 100
lines apart).

When you see the warning, you should remove the global 
declaration that comes after the assignment.  It doesn't 
seem worthwhile to add extra complexity to the compiler to 
handle this.

Maybe the function is too long if the two global decls are 
100 lines apart <0.9 wink>.
