bug#18228: 24.4.50; electrict-indent-mode bad indentation in python-mode

[Jorgen Schaefer <forcer@forcix.cx>]

Hi!
With a freshly compiled Emacs (git ref 3fc84165), I get the following
behavior. In a Python buffer with electric-indent-mode enabled, enter
this:


def foo():
    print "Foo"

def bar()


Adding a colon (":"") at the end of bar() will then indent the line to
the same indentation level as the "print" statement.

While this is the default indentation level for RET after the print
statement, I would expect that the colon will not reindent my current
line. python-mode can not know which indentation level is correct, so it
should not insist on one.
