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.

<p>Apart from the calculation of the Easter date, the definition <em>and</em>

obfuscation lurks in many places. Look at those macro identifiers.
What can be more obvious than a program that explicitly mentions the
grammatical constructs it is composed of? If you look at K&amp;RII A.9.3
you will find that a compound statement consists of an opening brace
followed by a declaration list followed by a semicolon followed by a
statement list followed by another semicolon and a closing brace. Nobody
can learn that by heart so I gently remind the reader by defining a
macro that expresses this clearly (line 25). This goes up to the
definition of a translation unit. Unfortunately, due to the IOCCC’s size
restrictions, I had to abbreviate some syntactic elements.
<code>ae</code> actually reads “assignment expression”. I had to stop at
some arbitrary point, so don’t waste your time trying to find out how
preprocessing tokens form type qualifier lists, cast expressions or
direct abstract declarators. Assuming the reader knows about these easy
to remember language elements is justified in my opinion.</p>

<p>The <code>-I/usr/include</code> in the build file is needed by gcc on
Solaris because <code>gcc</code>’s “fixed” header in
<code>gcc-lib/sparc-sun-solaris2.5/2.7.2/include/errno.h</code> is
broken (sort of) because it has <em>two</em> identical extern
declarations of errno. This leads to an error due to the redefinition of
main. The <code>-I</code> option makes sure the working
/usr/include/errno.h is found first, which shouldn’t cause any problems
on other systems.</p>
