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>Port 1701? Well this is not the l2f registered TCP/1701 protocol.
Sniff the traffic to/from that port. You will see HTTP client and server
traffic. The HTML content you may see is static and immutable. Nothing
funny with the HTTP status codes. Even the timestamp cookie, once set,
remains static throughout the session. The data appears to not be
transmitted within the binary content communicated between client and
server.</p>

confrontation between the <a

vessels must maintain silent running to avoid detection.</p>
<p>The battle is commemorated in the form of ASCII artwork depicting the
ships faced head-to-head in the page delivered by the web server. Plus,
the program source code is formatted in the shape of a Klingon Bird of

<p>Nibble Count Coding (file transfer protocol NCC-1701) is faster than
transmitting each individual bit as a short or long delay because it
sends each byte with 2 long delays whereas communicating individual bits

Coding is faster than applying Huffman Coding since that is designed to
