This change fixes two issues with the generated return table:
1. When specifying a list of strings in the 'description' field of a
return value, it shows them in Python list syntax on the resulting
web page, e.g. `['a', 'b', 'c']`.
2. When specifying more than one line for the 'sample' field, the
result table gets damaged in the HTML output.
In addition, this change re-arranges the HTML tags produced in the
generated RST file such that they line up nicely and can better be
checked by humans for completeness.
