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.

+Abusing The Rules:
+
+    Diomidis Spinellis
+    SENA S.A.
+    Kyprou 27
+    GR-152 37 Filothei 
+    Greece
+
+
+Judges' comments:
+
+    To use:
+	make spinellis
+
+    Try:
+	spinellis < spinellis.c
+
+    While code does not abuse the rules, its output surely does!
+
+    P.S. Does the source have any spelling errors?
+
+
+Selected notes from the author:
+
+    96% of the program lines (631 out of the 658) are comment text rendering
+    the program readable and understandable.  With the exception of the
+    two include file names (needed for a warning-free compile) the program
+    passes the standard Unix spell checker without any errors.  Checking
+    for spelling errors is considered very important for programs that are
+    so heavily commented.  This program is exactly 3217 characters long
+    through judicious use of white space.  Rule abuse?  Would I _ever_ abuse
+    the rules?
