This patch attempts to improve the consistency of the docstrings by
making the following changes:
- Rewraps all docstrings to a 79-character column limit.
- Adds a full stop at the end of every docstring.
- Removes any spaces after the opening triple-quotes of all
docstrings.
- Sets the hanging indent of multi-line docstrings to 3-spaces.
- Ensures that the closing triple-quotes of multi-line docstrings are
always on a new line indented by a 3-space indent.
