I use the following, it is probably not the best way to do it, seems to
work. Basically it sets the comment in italics in narrow margins for
drafts but ignores it for polished versions. It decides you a producing
a draft  if you have the overfull marker set, the draft style option
does this.

% comments - there are either ignored or set as a 'setcomment'
% depending on whether the draft option was selected.

\ifdim \overfullrule =0pt
       \def\comment{\@swallowall}
	\else\def\comment{\setcomment}
\fi
\ifdim \overfullrule =0pt
       \def\endcomment{\@endswallowall}
	\else\def\endcomment{\endsetcomment}
\fi

\newsavebox{\@rubishbin}
\newenvironment{@swallow}{\setbox\@rubishbin\vbox\bgroup}{\egroup}

\newenvironment{setcomment}{\list{}{\advance\leftmargin 5em
				\rightmargin\leftmargin}\item[] \em}{\endlist}
