$ 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.
