multiline auto-indent in python-mode

[Richard H Lee]

I'm using emacs 24.3.1 on cygwin64.

When in python mode I have a multiline section of code within a 
parenthesis, say:

print next(a for b in c
  if b = d)

If my cursor is at between 'd' and ')' and I hit space, emacs will 
indent the line I am on to the position of the opening parenthsis on the 
line above. Like so:

print next(a for b in c
           if b = d )

I just want python mode to not do any indentation as I have set up my 
own identation behaviour.

I tried setting python-mode-map to a fresh keymap, but it doesn't make 
any difference.
