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.

+
+    It is possible to write some kinds of programs in C without using reserved
+    words.  For very short and trivial programs, it usually isn't very hard to
+    write a variant using no reserved words, but with this program I want to
+    show that also non-trivial programs can be written this way.  This IOCCC
+    entry contains no reserved words (I don't count 'main' as a reserved word,
+    although the compiler gives it special meaning) and no preprocessor
+    directives.
+
+    The program is a small ray-tracer. The first line of the source code may
+    be modified if you want the resulting image to be of some other resolution
+    than the predefined. The 'A' value is an anti-alias factor. Setting it to
+    1 disables the anti-aliasing feature (this makes the output look bad), but
+    setting it too high makes the trace take a lot more time to complete.
+
+    The ppm image can then be viewed using an image viewer of your own choice.
+    (Running the ray-tracer may take several minutes, even on fast machines,
+    so be patient.)
+
+    I am very much aware about the fact that I'm breaking the guidelines. For
+    example, the word 'int' is a reserved word and therefore all variable
+    declarations are implicit.  There will no doubt be _lots_ of warnings,
+    no matter which compiler is used.  Still, the source code should be word-
+    length-independent and endianess-independent.
+
+    <humor>
+    Another reason for writing code without using reserved words is that many
+    text editors will make all reserved words turn BOLD when printed on
+    paper.  Since I care for the global environment, we shouldn't waste any
+    more laser toner, or ink, than necessary. Everyone should write C code
+    with no  reserved words, and our world will be a better place.
