+% \subsection{Fixing a problem with \BibTeX{}}
+%
+%    This will become a patch release for the kernel but for the moment
+%    we put it here in case some other issues show up. \BibTeX{}
+%    expects \texttt{.aux} files to contain lines
+%    \verb=\@input{filename.aux}= but the new new \LaTeX{}
+%    unnecessarily writes \verb=\@input{"filename.aux"}= and this
+%    upsets \BibTeX{} greatly. As it isn't necessary we take it out.
