hyperref expects the starred parts and chapters to have only one argument—
but we have two!
725 \AtBeginDocument{%
726 \def\@schapter[#1]#2{%
727 \H@old@schapter[#1]{#2}%
728 \@nschapterpreamble}%
729 \def\@spart[#1]#2{%
730 \H@old@spart[#1]{#2}%
731 \Hy@GlobalStepCount\Hy@linkcounter
732 \xdef\@currentHref{part*.\the\Hy@linkcounter}%
733 \Hy@raisedlink{\hyper@anchorstart{\@currentHref}\hyper@anchorend}}}%
We change the preamble for bibliography and index:
734 \def\@nschapterpreamble{%
735 \begingroup
736 \let\@mkboth\@gobbletwo
737 \Hy@GlobalStepCount\Hy@linkcounter
738 \xdef\@currentHref{\Hy@chapapp*.\the\Hy@linkcounter}%
739 \Hy@raisedlink{\hyper@anchorstart{\@currentHref}\hyper@anchorend}%
740 \endgroup}
We can add information about the file to the pdf metadata as well:
741 \let\ns@old@maketitle\maketitle
742 \def\maketitle{%
743 \hypersetup{pdfauthor=\@author, pdftitle=\@title}%
744 \ns@old@maketitle}

3.21 MakeIndex Style File
These lines will produce some warnings when running Makeindex as they try to
cover two different versions of the program:
746 〈∗ist〉
747 lethead_prefix "\\indexgroup{"
748 lethead_suffix "}\\nopagebreak\n"
749 lethead_flag 1
750 heading_prefix "\\indexgroup{"
