improved indentation and whitespace for markdown code blocks

Browse Source 
All code blocks in markdown have been intended by at least 4 spaces.

We add `--tab-stop=8` to all `pandoc(1)` executions in order to set
a better tab stop indentation, especially for tab intended code blocks.

Changed `bin/pandoc-wrapper.sh` VERSION from "1.5.3 2024-03-26"
to "1.6 2024-03-31".

Fixed `1991/brnstnd/sorta.README.md` so that the sorta code
is code blocks.

Removed unneeded paragraph group in copyright in `inc/footer.default.html`.

Fixed excess whitespace after list Author on entry `index.html` page.

Changed `bin/output-index-author.sh` VERSION from "1.5.2 2024-03-26"
to "1.6 2024-03-31".

Performed `make www` to perform the above and test under macOS.

TODO: Fix the problem of the initial line of code being extra intended.
TODO: Fix excess whitespace around code that is inline.

<p>To see if your compiler has the problem described in the Judges’ remarks below,
try:</p>
<div class="sourceCode" id="cb5"><pre class="sourceCode sh"><code class="sourceCode bash"><span id="cb5-1"><a href="#cb5-1" aria-hidden="true" tabindex="-1"></a><span class="ex">./westley.alt</span></span></code></pre></div>

<p>Does it show the same output as <code>westley</code>?</p>
<h2 id="judges-remarks">Judges’ remarks:</h2>
<p>Your compiler must parse</p>
<div class="sourceCode" id="cb6"><pre class="sourceCode c"><code class="sourceCode c"><span id="cb6-1"><a href="#cb6-1" aria-hidden="true" tabindex="-1"></a><span class="pp">#define _ </span><span class="op">-</span><span class="pp">a</span></span>

<span id="cb6-2"><a href="#cb6-2" aria-hidden="true" tabindex="-1"></a> <span class="op">-</span>_</span></code></pre></div>
<p>as <code>--a</code> and not <code>-(-a)</code> or some other tokenized form. Some strictly
conforming ANSI C Preprocessors may object to this: for such
compilers, you can elide the non-standard token-pasting requirement
by changing the #define line to:</p>
<div class="sourceCode" id="cb7"><pre class="sourceCode c"><code class="sourceCode c"><span id="cb7-1"><a href="#cb7-1" aria-hidden="true" tabindex="-1"></a><span class="pp">#define _ F</span><span class="op">--&gt;</span><span class="bn">00</span><span class="op">||</span><span class="pp">F</span><span class="op">-</span><span class="pp">OO</span><span class="op">--;</span></span></code></pre></div>
<div class="sourceCode" id="cb7"><pre class="sourceCode c"><code class="sourceCode c"><span id="cb7-1"><a href="#cb7-1" aria-hidden="true" tabindex="-1"></a> <span class="pp">#define _ F</span><span class="op">--&gt;</span><span class="bn">00</span><span class="op">||</span><span class="pp">F</span><span class="op">-</span><span class="pp">OO</span><span class="op">--;</span></span></code></pre></div>
<p>This is what the modified code in <a href="westley.c">westley.c</a> does whereas the alt
code is the original.</p>
<p>You might enjoy looking at the output of:</p>
<div class="sourceCode" id="cb8"><pre class="sourceCode sh"><code class="sourceCode bash"><span id="cb8-1"><a href="#cb8-1" aria-hidden="true" tabindex="-1"></a><span class="fu">cc</span> <span class="at">-E</span> westley.alt.c</span></code></pre></div>
