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' comments:
+
+    To use:
+	make horton
+	./horton A B C D
+
+	A, B, C, D are numeric arguments (try 3 2 1 0).
+
+    Try to figure out how this program prints, for a given slope, the
+    right character.  And for extra credit, try to figure out which
+    character is at the bottom on this hint file.  :-)
+
+    This confuses cb greatly. See gtplot.c for an unobfuscated/enhanced 
+    version.  To compile it:
+
+	make horton.alt
+	./horton.alt A B C D
+
+	A, B, C, D are numeric arguments (try 3 2 1 0).
+    
+
+Selected notes from the author:
+
+    Run it with any 4 numeric arguments, e.g. prog 3 2 1 0.  Play with the
+    numbers to get a pleasing result, or use it for your high school algebra
+    class.
+
+    SPOILER:
+
+    As should be obvious from 20 feet away, the program is a cubic plotter.
+    It plots against certain artists, splattering their cubes with graphs
+    of their cubic equations.  Those dastardly arguments are mere coefficients,
+    cogs in the wheels of the grand plot to overthrow the cubics!
+
+    Oh, by the way, it uses a self-contained graphtab and frame buffer.
+    It's easily modified to graph *any* 96x160 bitmap on a dumb terminal.
+
+    See the gtface program for another example.  Try:
+    
+	make gtface
+	./gtface < gtface.data
