+\texttt{mergedate=basic} is similar in concept but more economical.
+It will always omit the date specification if the date is a bare year
+number:

+\texttt{mergedate=maximum} strives for maximum compactness. Even the

+\texttt{mergedate=true} is an alias for \texttt{mergedate=compact}.
+This is the default setting.
