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 ctk

+    Try:

+
+    No matter how careful you are, this guy eventually crashes.  Most people
+    can make at least one successful road trip without crashing.
+
+    This is, of course, another of the retro games.

+Selected Author's Comments:
+
+    This is a game based on an Apple ][ Print Shop Companion easter
+    egg named 'DRIVER', in which the goal is to drive as fast as
+    you can down a long twisty highway without running off the
+    road.  Use ',./', '[ ]', or 'bnm' to go left, straight, and
+    right respectively. Use '1234' to switch gears. 'q' quits. The
+    faster you go and the thinner the road is, the more points you
+    get. Most of the obfuscation is in the nonsensical if statements
+    among other things. It works best on the Linux console: you
+    get engine sound (!) and the * Lock keyboard lights tell you
+    what gear you're in (none lit=4th).  The 'q' argument (no
+    leading '-') will silence the sound. It won't work on a terminal
+    smaller than 80x24, but it works fine with more (try it in an
+    XTerm with the "Unreadable" font and the window maximized
+    vertically!).
