Fix indentation issues reported by flake8

- E121 continuation line under-indented for hanging indent
- E122 continuation line missing indentation or outdented
- E125 continuation line with same indent as next logical line
- E126 continuation line over-indented for hanging indent
- E127 continuation line over-indented for visual indent
- E128 continuation line under-indented for visual indent
- E129 visually indented line with same indent as next logical line
- E131 continuation line unaligned for hanging indent

Fixed automatically with autopep8:

  git ls-files | grep py$ | xargs autopep8 --in-place \
    --select E121,E122,E125,E126,E127,E128,E129,E131
