Landon Curt Noll a1c86c8a7a add original C links to entry navigation bars
The navigation bar for a winning entry now has a "_Original C_" link
(between the ✅ and the Inventory on the right hand side) so that one
may easily view the original C code that was submitted for IOCCC judging.

Ran `make www timestamp` to perform the above.

<p>While it may not have been the intention of the author, the
judges noted that the C pre-processed version (with the <code>#include</code>s
left intact) looked very much like a rat “dropping core”. See
<a href="https://github.com/ioccc-src/winner/blob/master/1995/garry/garry.alt.c">garry.alt.c</a> and judge for yourself!</p>

<h2 id="judges-remarks">Judges’ remarks:</h2>
<p>The author was kind enough to provide a less obfuscated version of
the source called <a href="https://github.com/ioccc-src/winner/blob/master/1995/garry/garry.fmt.c">garry.fmt.c</a>.</p>
<h2 id="authors-remarks">Author’s remarks:</h2>
<p>This program is a file filter, designed to do environment-expansion and
incorporating the ability to create binary from escaped data in the
environment variables.</p>
<p>The calling syntax is pretty simple, just use it with <code>stdio</code>-redirection
or inside pipelines, e.g.:</p>
<pre><code> ./garry &lt;file_to_convert &gt;converted_file</code></pre>
<p>or</p>
<pre><code> cat all_my_files/* | ./garry | lp</code></pre>
<p>The syntax of the conversion of the input file is as follows: To include the
value of an environment variable in the output file, place the name of the
variable between <code>$</code>-signs in the input, e.g.:</p>
<pre><code> My Home-Directory is: $HOME$
I&#39;m using the path: $PATH$</code></pre>
<p>Unknown Env-variables or malformed expressions are ignored and kept intact.</p>
<p>Additionally, the filter replaces escaped octal values in the environment
variables by their binary representation, e.g.:</p>
<pre><code> $ TEST=&quot;\110\145\154\154\157&quot;
$ export TEST
$ echo &#39;$TEST$&#39; | ./garry
Hello</code></pre>
