bug#17670: 24.3.90.1; no indent from C-j in Python shell

[Andreas Röhler]

emacs -Q

M-x run-python

Insert at prompt: "if True:"

C-j should indent but goes to BOL

Running fails as expected:


Python 2.7.3 (default, Mar 14 2014, 11:57:14)
[GCC 4.7.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> if True:
print(45)
...   File "<stdin>", line 2
    print(45)
        ^
IndentationError: expected an indented block
>>>
