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.

+	make dhyang
+
+    Try:
+
+	cc dhyang.c -o saitou
+	./saitou > aku.c
+	cat aku.c
+
+	cc aku.c -o soku
+	./soku > soku.c
+	cat soku.c

+	cc soku.c -o zan
+	./zan > zan.c
+	cat zan.c

+    A beautiful combination of solving several different problems, but
+    mostly, the single most impressive layout we've ever seen.  Many
+    programs have *one* interesting layout; this one has four.
+
+    It may be informative to run the code through a "beautifier", to
+    study it, but the layout itself is where most of the interest lies.

+
+    Instead of making one self reproducing program, what I made was a
+    program that generates a set of mutually reproducing programs, all of
+    them with cool layout!
+
+    For your enjoyment:
+       1. Compile saitou.c
+       2. Run a.out and pipe output to another .c file
+       3. Compile that file
+       4. Repeat steps 2 and 3 until eventually the output cycles
+
+    To interpret the output: the saitou.c is an image of Saitou Hajime,
+    which eventually generates three sources files that are images of
+    "aku soku zan" (sin swift slay), Saitou's motto ;)
+
+    For best viewing, set tab spaces to 8 characters, and set your
+    terminal fonts to as close to square as possible.  I hate to do this
+    but you know, size...
+
+    saitou.c and all its output compiles with gcc if your OS uses ASCII
+    character set.  No file is included and all functions assume default
+    int return type (a source of compile warnings)
