I'm away from my desk so I can't look up the ref, I'm sorry. But a kern is nonbreakable, either horizontal or vertical. My guess is I want the rule to not be a place for a page break

Dear Jim,<br>
<br>
I am propagating your r633 to the French version. I fell accross this<br>
new example in node \footnote :<br>
<br>
\renewcommand@{\footnoterule@}@{% Kerns keep it from taking up vertical space<br>
\kern -3pt % This -3 is the negative of<br>
\hrule width \textwidth height 1pt % the sum of this 1<br>
\kern 2pt@} % and this 2<br>

My understanding of the TeX \kern command is that it controls the<br>
