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 program plays the Game of Life.
+
+    Life is a cellular automaton invented by J. H. Conway, in which each of
+    a rectangular grid of cells can be alive or dead, and cells with more
+    than 3 or less than 2 (out of 8) live neighbours die, and empty cells
+    with exactly 3 neighbours give birth.
+
+    Some notes: the "STAT n" information does not have to be present in the
+    initial configuration;  the initial configuration should not have live
+    cells around the edges; the grid should be a perfect rectangle.
+
+    Further features: the current generation number is preserved, and the
+    grid automatically resizes itself as the object gets too big or too
+    small.
+
+	When writing this program, my goal was to make each cell in the life
+	grid expand to the code which calculates the fate of that cell.  In
+	addition, the resulting program is a single expression, which makes it
+	necessary to recurse on main in two "directions" simultaneously.
