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.

+    generate its message to the world.  One program's error is another

+    This program is yet another "Hello World." program with a twist.  The
+    string Hello World has been encoded in the error messages the compiler
+    generates when compiling the source.
