/// Trailing trivia is represented by a call to <c>%trailing</c> in a node's
/// attribute list; each argument to %trailing represents one piece of trivia.
/// <para/>
/// In the current design, this method has a side-effect of recreating the %trailing
/// node at the end of the attribute list, and if there are multiple %trailing
/// lists, consolidating them into a single list, but only if the specified <c>trivia</c>
/// list is not empty.</remarks>
