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.

+,-,*,/ | Arithmetic operations, priority of * , / over +,- is

Im | Extract the imaginary part, i.e.: Im(a+b*i) is b+0*i.

Ln | Calculates the principal value of the natural logarithm, i.e.

<p>Each piece is a bitmap, and represents a 3x3x3 cube.</p>
<p>For instance the first piece is <code>186</code> - this is <code>010111010</code> in binary.
Written out like this you can see that it is the cross shaped piece:</p>
<pre><code>010
111
010</code></pre>
<pre><code> 010
111
010</code></pre>
<p>The other pieces are defined similarly. Most of the rest require more
than one layer, such as piece 3 (<code>1426</code>):</p>
<pre><code>000
000
010
<pre><code> 000
000
010
110
010
010</code></pre>
110

010</code></pre>
<p>Imagine the two layers on top of each other, and you should see this
shape:</p>
<pre><code> +---------+

<h3 id="making-your-own-shapes">Making your own shapes</h3>
<p>The program is in fact a general solver - you can change the shape of
the pieces, and provided that a solution is possible, it will be found.</p>
<p>For example, if you modify line 13 of the source like this, the program
will solve for a different piece set:</p>
