bug#15163: 24.3; python-mode, electric colon bug

[Alexis Roda]

Electric colon don't indent when used in conjunction with
newline-and-indent in some nested statements.

To reproduce:

emacs -Q /tmp/bugtest.py

and type:

 i f SPC a : C-j i f SPC b : C-j p a s s C-j e l s e : C-j p a s s C-j 
e l s e :

you'll get:

if a:
    if b:
        pass
    else:
        pass
        else:

The last 'else' isn't indented properly.
