force use of pandoc version >= 3.1.12.2

Browse Source 
The `bin/pandoc-wrapper.sh` tool will verify that the ssytem
has a recent enough version of `pandoc(1)`.

We explain why we insist on `pandoc(1)`. version >= 3.1.12.2
in comments where the $PANDOC_MIN_VERSION is set.

Added `--wrap=preserve` as a default argument to `pandoc(1)`.
While this change will impact every HTML file generated,
we believe this will improve the ability of someone to look
at the generated HTML and correlate with the original markdown.

Changed `bin/pandoc-wrapper.sh` VERSION from "1.4.2 2024-03-17"
to "1.4.3 2024-03-18".

Performed `make www` to achieve all of the above and to generate
HTML using the new  `--wrap=preserve` `pandoc(1)` mode.

that, at first blush, this looks like a self-reproducing program.</p>

<h2 id="authors-remarks">Author’s remarks:</h2>
<p>This program doesn’t require any special build options, other than
that it uses <code>sin(3)</code> and <code>cos(3)</code> and hence
requires the math library.</p>
<p>You will almost certainly get a compiler warning because I declared a
bunch of global <code>int</code>s without types. The code looks better
this way, though, I think. There are also no <code>#include</code>s, so
there may be warnings for undeclared references to
<code>printf(3)</code>, etc. There’s a chance that my failure to include
<code>math.h</code> or declare <code>sin(3)</code> or
<code>cos(3)</code> will make the <a
href="https://en.wikipedia.org/wiki/Doughnut">donut</a> not render

<p>You will need some kind of VT100-ish emulation; so while this
compiles and runs OK in Windows, you will need PuTTYcyg or something
like that.</p>

<p>The shape of the source gives a hint about its output: it’s a little
animation of a shaded donut rotating over an infinite checkerboard. Like
many IOCCC entries, it is thus self-documenting.</p>
<p>I wanted to create something as “pure” as I could - meaning that the
entire source code is shaped into a work of art, without being prefixed
by any <code>#define</code> hacks, or even <code>#includes</code>,
<em>and</em> is portable enough to not require any special libraries to
do the animating. I achieved this with two standard escape codes for
clearing the screen and moving the cursor back to the top-left.</p>

<p>The donut isn’t raytraced. It’s much simpler than that.</p>

<p>There are three main pieces to this program: the donut, the
checkerboard, and the ASCII logo. The first two are programmed in a
straightforward way (with <a
href="https://en.wikipedia.org/wiki/Z-buffering">z-buffering</a> even!),
but the mathematics for drawing them is “optimized”. The ASCII logo has
been shrunk into the smallest I could make it by any means
necessary.</p>
