git mv *.hint -> README.md

There is one exception:

    $ find . -name '*.hint' -execdir git mv '{}' README.md \;
    git statufatal: destination exists, source=1992/albert/albert.hint, destination=1992/albert/README.md

Looking at the two files they differ quite a bit so I've not changed it.
I'll bring this up on GitHub.

+
+    Questions to ponder:
+
+	Can you determine the relationship between the input and the
+	resulting numeric output?
+
+	The program was not designed to process files with a certain
+	octet value, what value is that?
+
+    Hint and Extra Credit:
+
+	This entry points our a minor flaw in the IOCCC rules that has
+	been around since 1992.  It processes a certain octet value in
+	a way that differs from a strict reading of one of the
+	official IOCCC rules.  What is the rule and what is the octet
+	value?

+Selected Author's Comments:
+
+    The main obfuscation is the way characters are recognized, which is
+    done by matching the bit patterns.  Minor obfuscations are:
+
+    - Useless layout.
+
+    - Useless variable names.
+
+    - Recursive main() instead of 2 loops (over input characters and over
+    bits in the character).
+
+    - ? and || instead of if statements.
