(py-comment-indent-function): A replacement for
comment-indent-function's default lambda value (in simple.el), this
version finally kills this nit: auto-filling a comment that starts in
column zero with filladapt turned off would cascade the #'s to the
right.

Now auto-filling seems to work with or without filladapt, and with the
comment starting in any column.

(python-mode): Set comment-indent-function.
