[Libguestfs] [libnbd PATCH 03/23] generator: wrap "python/libnbdmod.c" at 80 characters

[Laszlo Ersek]

Break the fields of each PyMethodDef structure initializer to separate
lines.

While at it, drop the superfluous (char*) cast from the
"PyMethodDef.ml_name" field initializer
<https://docs.python.org/3/c-api/structures.html#c.PyMethodDef>.
(According to commit bf0eee111fc3, "Add Python 3 bindings.", 2019-05-11,
we don't target Python 2.)

Effect shown on the currently longest line in "python/libnbdmod.c":

> -  { (char *) "aio_connect_systemd_socket_activation", nbd_internal_py_aio_connect_systemd_socket_activation, METH_VARARGS, NULL },
> +  {
> +    "aio_connect_systemd_socket_activation",
> +    nbd_internal_py_aio_connect_systemd_socket_activation,
> +    METH_VARARGS,
> +    NULL
> +  },
