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.

+
+Selected notes from the author:
+
+    This filter program is really not obfuscated code.  It compiles cleanly
+    with an ANSI C compiler and comes with user documentation that even a
+    blind person could read.
+
+    The program is a bi-directional filter with the output of the program 
+    suitable for its input.  The output of this program, when used as input,
+    undoes the original program filtering.
+
+    This program accepts any alphanumeric text that has lines less than 100
+    characters.  The user is encouraged to use the program's source as input
+    to the executable.
+
+    This program is best appreciated on a tactile monitor.
