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 notes:
+
+	Run this with a single digit argument (or wait a long time).
+
+	There are 2 versions of this program, the one that was entered,
+	and one that was changed by the judges to be more portable. The
+	makefile runs the latter version by default.
+
+	The blank line at the beginning of the source is mandatory.
+	Do you know why?
+
+	The shell script run by the makefile joins lines that may be
+	cut up by mailers.  The file "fubar.orig.c", for example, needs
+	the 6th and 7th lines joined together (with a space between
+	them) to recreate the original entry.  If you fix the file, you
+	will need to change the last 8 linnes of "fubar.orig.sh" to read:
+
+		cp fubar.orig.c ouroboros.c
+		chmod +x ouroboros.c
+		csh ouroboros.c $1
+		rm -f ouroboros.c x1 x
+
+	The more portable version, "fubar.c", can be fixed by joining the
+	7th and 8th lines in the same way.  As well, if you fix "fubar.c"
+	you will need to also change the last 8 lines to "fubar.sh" to read:
+
+		cp fubar.c ouroboros.c
+		chmod +x ouroboros.c
+		csh ouroboros.c $1
+		rm -f ouroboros.c x1 x
+
+Selected notes from the author:
+
+	In a nutshell, this is probably the slowest and most
+	obnoxious factorial program ever written.  Unfortunately, 
+	the name of the C source must be "ouroboros.c"; the name is 
+	hard-coded into the program.  
+
+	The source is a legal shell script and a legal C program.  
+	The shell script compiles itself, and then executes the
+	resulting binary, giving the source as input.  The program 
+	works by successively modifying #define lines each pass through.
+
+	Both "indent" and "cb" will damage the program, "indent" 
+	much more so.
