% we now see that the label has for item three has been defined
% differently, and that for item four differently again.  note the
% reference starting a new sentence.
\item fourth item, defining a fancy label in a different format (see
  also item~\ref{third}).  \Ref{fourth} shows how a sentence may start
  with reference to a fancy label; note that it's the \emph{label}
  that's fancy, so the second change to the label format only affects
  the labels defined after it.  \label{fourth}
