`python-mode' provides it's own `beginning-of-defun-function' which
doesn't seem to rely on `beginning-of-defun-raw'.  Hence, setting that
in `python-mode' is likely just paranoia.

That comment should probably serve to justify why the subsequent code in
the doc-string is indented.

Anyway: `open-paren-in-column-0-is-defun-start' is a user option
explained thoroughly in the Emacs manual.  If a major mode does not
override the default setting, users should know where
`beginning-of-defun' gets them when they customize it to nil.
