There are two typos in the definition of the variable
`electric-indent-functions-without-reindent' in lisp/electric.el:

- its docstring mentions a non existing `line-indent-function' instead of the
  correct `indent-line-function';

- its value contains a reference to a non existing `py-indent-line' function,
  that should really be `python-indent-line-function'.

The attached patch fixes both issues.
