Definition lists

The term is given on a line by itself, followed by one or more definitions. Each definition must begin with : (after 0-2 spaces); subsequent lines must be indented unless they are lazy paragraph continuations.

The list is tight if there is no blank line between the term and the first definition, otherwise loose.
