% \rightskip=0pt plus 4em       % ragged right
% \spaceskip=1em                % forces ONE space between words
% \frenchspacing        suppresses extra blanks after punctuation -don't

% the section number and title.  This comes out as no space in the doc file 
% so we add a space to numberline, and expand tempdima by one em to allow 
% for it.  Also, go out of math mode for the dot in the leader.  Dots in 
% math mode turn out to be colons!
