The function arguments in the documentation comments were using field
list, which caused text overflow in the generated documentation and
generally resulted in poor formatting. Let's use paragraphs for
the argument descriptions instead.
The documentation comments are written in reStructuredText, but
currently, they use inconsistent indentation. Standardize all the
documentation comments to use a four-character indentation.
