bug#20742: 24.5; python mode indentation fails pep8

[Tommi Komulainen]

The automatic indentation and manual reindenting with
indent-according-to-mode puts the closing bracket in wrong place that
makes pep8/flake8 flycheck complain:

print("hello",
      "world",
)
E124 closing bracket does not match visual indentation

The bracket needs to align with the first thing after the opening
bracket if it's on the same line i.e.:

print("hello",
      "world",
      )

The automatic indentation doesn't cause any errors if there's a newline
after the opening bracket though:

print(
    "hello",
    "world",
)
