$ emacs - q
Visit a new Python buffer and type:
a = b (0)
C-M-f at the beginning of the buffer moves the point immediately to the end of line. Expected is point after 'a', as in other modes. As another visible and annoying effect, C-M-k kills more than expected, thus breaking editing habits.
Note that C-M-b from the end of line moves point to '(', then to 'b', then to 'a', just as expected.
