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.

+Selected notes from the authors:
+
+    A classic problem in computer science is known as the Towers
+    of Hanoi.  It involves a set of different-sized disks mounted
+    on one of three pegs.  The object is to move the pile of disks
+    to one of the other pegs.  You may only move one disk at a
+    time, and there is an additional constraint that a disk may
+    never be placed on top of a smaller disk.
+
+    Our program solves the Towers of Hanoi problem.  Well, that's
+    not exactly true; actually, it's the compiler that solves the
+    problem.  The resulting program just prints out the correct 
+    solution.
+
+    How do you trick a compiler into actually solving the problem?
+    First, you must tell it how many disks you wish to solve it
+    for.  This is done by defining the symbol 'n' on the compile
+    line.  For instance, to cause the compiler to solve the Towers
+    of Hanoi problem with four disks, you would compile the program
+    like this:
+
+        gcc hanoi.c -o hanoi -Dn=4
+
+    A default value of 5 will be used for n if you do not define
+    it on the command line.  The value of n cannot be greater than
+    fifteen (the compiler we used to test has a limit on the #include
+    depth).  The compiler then solves the problem using binary 
+    arithmetic based on whether particular symbols are defined or not.
+    
+    To loop, the program #include's itself.  This is, of course,
+    expensive; one compile we did with n=14 took about fifty
+    minutes to compile on our system (compiling with n=15
+    caused our system to crash).
+
+    The resulting program that the compiler generates simply
+    prints out the answer.  Did I say "simply"?  Actually, the
+    whole resulting program consists of a single printf statement,
+    consisting of a massive string constant of length 35*(2^n-1),
+    followed by 3*(2^n-1) integers which get formatted into the
+    string.  For our n=14 run, this adds up to a string constant
+    of length 573405, followed by 49149 integers delimeted by
+    commas.  (Generating the string constant depends on the
+    ANSI C feature in which adjacent character strings are
+    catenated; a version that does not use this feature has been
+    included for people who can only run K&R).  A good way to see
+    the resulting program (on a Unix system) is to do the command
+
+        gcc hanoi.c -E -Dn=5 | grep -v \# | grep -v ^\$
+
+    For an odd number of disks, the program will provide a
+    solution wherein the disks end up on peg 2; for an even
+    number of disks, they will end on peg 3.  This should 
+    provide some hint as to what sort of algorithm is used.
+
+    We have included a "spoiler" version of the program, with
+    meaningful symbol names and comments, but we encourage you
+    to try to decipher the program without it...
