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.

+Judges notes:
+
+	Run this program using your favorite text file as input.  Files
+	such as mailboxes, man pages and usenet articles are especially
+	recommended.  You will get different output each time you run it.
+
+	Run the program this way:
+
+		ovdluhe < textfile
+
+	The program stops when it reaches the end of the template buffer 
+	by chance or is killed.
+
+Selected notes from the author:
+
+	This program implements an "Eddington ape" - it generates
+	random text from a supplied template.  The template text file
+	is read through stdin.  The larger the template, the better the
+	result.  A maximum of 2**12 chars are used. From the template,
+	the program calculates the statistics of chars that immediately
+	follow a given string (correlator string) of a certain length
+	(currently 4 - can be varied by changing the definition for P
+	accordingly).  A character is randomly chosen, weighted by its
+	probability to occur after the correlator string.  That
+	character is printed to stdout and placed at the end of the
+	correlator string, whose first character is discarded.
+	Meaningful words are therefore usually preserved, the effect on
+	sentences can be dramatically random.
+
+	You might want to vary the definition of P between 2 and 10 and
+	observe the result.
