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>As they say, “Lather, rinse, repeat”! :-)</p>
<p>If you have the time :-), figure out how this small 1-line entry works!</p>
<h2 id="authors-remarks">Author’s remarks:</h2>
<p>At 130 characters of C code (without the newline at the end), this
should fit into the “1-liner” category.</p>
<p>The clock numerals are rendered as an old fashioned 7 segment display.
The encodings for which segments light for which number, and for where
each segment appears on screen are hidden in the two strings.</p>
<p>When reading the program, you may want to refer to a table of operator
precedence (try <code>man 7 operator</code>) - careful choices were made to keep the usage
of brackets to a minimum, and to keep the character count as low as possible.</p>
<p>One interesting bit of obfuscation - the null at the end of the second
string actually forms part of the lookup table.</p>
<p>Intel CC warns about the lack of a declaration for the argument to <code>main()</code>.
(<code>gcc</code> does not notice this though, even with <code>-Wall</code>.) But anyway it can
easily be declared as <code>int</code> at the expense of 4 more characters.</p>
<p>I’m not sure of the effects on a hard disk of rewriting the same file
multiple times per second for a long time. Run at your own risk!</p>
