bug#18432: 24.4.50; python-mode, elif line indentation

[Sho Takemori <stakemorii@gmail.com>]

Dear developers,

In a Python buffer, I have the following code.
Here _ indicates the position of the cursor.

if (a == 1 or
     a == 2):
     pass
elif (a == 3 or_a == 4):

When I press C-m, then this code becomes as follows:

if (a == 1 or
     a == 2):
     pass
elif (a == 3 or
a == 4):

I expected the following:

if (a == 1 or
     a == 2):
     pass
elif (a == 3 or
       a == 4):

Also I cannot change the indent level at the final line by TAB.

This may not be a bug.
But the 4th line and 5th line lack the compatibility with
the 1st line and the 2nd line.

Best Regards,
Sho Takemori
