Subject: py-indent-line comes from the external python-mode

Further investigation reveals that the external python-mode (that is,
https://gitlab.com/python-mode-devs/python-mode) effectively implements the
`py-indent-line' function, so that was the target.

I guess the attached patch should be ignored.

The docstring typo seems real, though.
