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.

+Best abuse of C constructs:

+    	Arch D. Robison
+	University of Illinois at Urbana-Champaign
+	1304 W. Springfield Ave.
+	Urbana IL 
+	61801
+	USA
+
+Try: robison 80 10
+     robison 40 16
+
+The first and second parameters are optional.  You might also try:
+
+     robison 80 2   <--- can you find the bug?
+     robison 80 -246
+
+The author says:
+
+    This program shows that C has many unnecessary constructs, in fact
+    only "while","--", and ">=" are required.  (The two assignments at
+    the beginning could be avoided if "atoi" was rewritten with this
+    new paradigm.)  Note that the lack of both the controversial "goto"
+    and assignment statements makes the meaning crystal clear.  The current 
+    ANSI committee should look into this practical simplification of C.
+
+The following might make an interesting benchmark:
+
+     robison 100    
+
+[Amdahl 5890-300E with System V cc: 8.40 seconds]
+
+We suggest that you C preprocess and perhaps C-beautify this program.
+All is not what it may appear to be in this program.  When does a whi1e
+not take a while to execute?
