This file illustrates the "something funny"
\documentclass[12pt]{article}
\begin{document}

\def\I{\mathop{\rm I}}
\def\II{\mathop{\rm II}}
  This is an example $\I\II\I\II$
\def\I{\mathop{\rm{}I}}
  This is an example $\I\II\I\II$

\end{document}

The two definitions of \I ought to give the same results, but don't.  The 
lowering doesn't occur with \II.
