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.

+    The only way to win is not to play.  No, really; you can't actually win.
+    :)
+
+    The formatting really wants a wide screen; if you can't read it that way,
+    it's the standard "three triangles around a circular" logo for nukes.
+
+    This is a pretty straightforward game.

+    What this program does:
+
+    It plays Missile Command, complete with MIRVs, smart bombs,
+    extra cities, and scoring.
+
+    Command line arguments and input files are ignored.
+
+    To play, just point and click where you want your ABMs to explode.
+
+    The score is 10 points for each missile which is destroyed before
+    it reaches the ground, -1 point for each ABM used, and 100 bonus
+    points for each city left at the end of a level.
+
+    The game ends when you lose all your cities, although you will have
+    to wait until the level finishes raining down to see your final score.
+
+
+
+    The main obfuscation technique is the need to compress the code to fit
+    all the functionality within the size limits.  I could not have included
+    smart bombs without the rule excluding { } ; characters in the counts.
+    All of the #defines are there to reduce code size.
+
+    On the other hand, I did waste a few characters in order to include
+    some rather obfuscated math in the program.  It uses fixed-point
+    arithmetic, resulting in the overuse of bitwise shift operators.
+    Another example is (x|1), which is used in a couple different ways.
+    The purpose of A/(x|1) is probably obvious, but what does (x|1)%2 do?
