On the other hand we may want all lists to
\begin{enumerate}
 \item use less space around them;
 \item and no space between items and paragraphs.
  \par Instead paragraphs should have some
       indentation inside the list.
\end{enumerate}
Do these setting also apply
\begin{center}  here? \end{center}
Clearly no! See discussion below.
