Martin Ruckert's talk at TUG'24 about 'Profiling TeX' (watch on YouTube:
https://www.youtube.com/live/d7vTW7PR0B4?t=7795s) and the ensuing private
discussion with him lead me to inspect the relevant parts of
'cwebacromac.tex' (and 'pwebmac.tex') more closely in order to address
the performance issues with certain large C/WEB programs.
The most glaring example is MP.W, where every advanced TeX engine (for
PDF and HINT) virtually stops for 1--2 seconds (on my machine) at two of
the index pages because of the huge lists of section references for the
variable 'mp' and the type 'MP' that are used 'everywhere'. (See below.)
At this point, we haven't solved the quadratic performance behavior yet.
However, the main changes applied in this commit at least slightly
improve the macros and their application. In the overall context of the
'knuth-pdf'/'knuth-hint' packages, the 'index issue' reported by Martin
becomes more or less irrelvant. The script 'makeall' produces 58 PDF
documents in the main run. With all optimizations applied, the runtime
is reduced by mere seconds from '1m7s' to '0m59s' (with 'pdftex').
(a) '\pdflink' and '\HINTlink' have lost their second parameter, which
was only used with 'plain TeX plus dvipdf' and 'XeTeX' anyway. This cut
down the replacement strings significantly. In one example I observed a
runtime improvement of about twenty percent (2--3 seconds) by this
change alone.
(b) Macros '\makeoutlinetoks' and 'outilnedone' swallowed the
surrounding macro calls, thus simplifying their application.
(c) '\newcount\countC' was replaced with '\newif\ifhavenum' to avoid
arithmetic with '0' and '1' for a simple Boolean operation.
(d) '\newcount\countD' was renamed to '\countNOS'. (Unrelated.)
In order to address the 'worst' CWEB code MP.W mentioned above, I
changed both the macros and the 'makeall' script. My local MP.CH changes
the '\inx' macro to address two 'Overfull \hboxes', so it is easy to
remove the use of '\pdfnote' when setting up the index. Instead,
'makeall' invokes SED to amemd the MP.IDX file created by CWEAVE with
the necessary '\pdflink' macro invocations for all section numbers in
one fell swoop. This cuts the processing time for MP.TEX in half (!!).
However, I do not intend to incorporate this approach into
'cwebmac.tex'/'pwebmac.tex' because this would most likely require
'--shell-escape' and become too system-dependent. For small to midsize
C/WEB programs, this would show minor improvements anyway.
Watch this space for possible further improvements. (I'll hold back the
releases of 'CWEB 4.12' and 'pwebmac 5.0' for the time being.)

This might rather be documented in 'cwebman.tex' together with '\def\9'.

There's a type mismatch (probably copy-paste-error) for
'pdf_font_has_space_char', defined as '^boolean' in section 821,
in sections 1502 and 1518.
See https://tug.org/pipermail/tex-live/2024-July/050773.html for the
initial bug report.

Maybe someone wants to use a different set of fonts in future.
'\eightrm' is already loaded in 'cwebmac.tex'.

The classic 'manfnt' font has 'METAFONT' in several sizes; 9pt (?) is
used on the titlepage of MFT.WEB as '\logo hijklmnj'. Pick the missing
'S' (in 10pt) for the 'MetaPost' logo in the main text from the separate
'logo10' font.

With 'pdfctwimac.tex' there's no table-of-contents page (yet), so the
'\datecontentspage' never appeared 'in print' (together with '\datethis'
on the first page) with any of the PDF engines.
With 'pdfctproofmac.tex' used with HiTeX, the two '\date' macros showed
up in 'ctwill.hnt'. Similar to the other three CWEB modules 'without
changes', we get rid of the '\datecontentspage'.

Note that webman.pdf will have a link to the 'Holon Programming' project
on Github.

The TeX macro '\title' is used far too often, both in the TeX parts and
in an index entry that produces an 'Overfull \hbox'.
Curiously enough, I was able to produce a 'core dump' from 'xdvipdfmx' with
this twisted change (the @x and @y parts should, of course, be flipped):
@x
begin print(' !Sorry, DVIcopy capacity exceeded ['); print_packet(p);
@.Sorry, DVIcopy capacity exceeded@>
@y
begin print(' !Sorry, ',title,' capacity exceeded ['); print_packet(p);
@.Sorry, {\title} capacity exceeded@>
@z
xdvipdfmx: ../../../texk/dvipdfm-x/dpxutil.c:454: ht_lookup_table: Assertion `ht && key' failed.

In some rare cases, CWEAVE inserts '\7' instead of '\6' after
preprocessor commands (maybe related to '@!' as well).
