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.

+	Netherlands
+
+Judges notes:
+
+	This is a character terminal version of the TETRIS program. 
+	It runs on a VT100 compatible terminal or emulator.  It is 
+	best used at 4800 baud or more.
+	
+	Usage:
+
+		tromp [drops_per_sec  [cmd_string]]
+		tromp.s5 [1  [cmd_string]]
+	
+	By default, "drops_per_sec", the number of times an object
+	will drop in a second, is 2.  The default "cmd_string" is
+	"jkl pq".  The first 6 characters of "cmd_string" relate
+	to the following 6 game commands:
+
+		j - left
+		k - rotate
+		l - right
+	  <space> - drop
+		p - pause
+		q - quit
+	
+	Specifying "cmd_string" allows one to re-define the commands.
+	The pause command pauses the game, clears the screen and
+	prints the current score.  To un-pause, type the pause
+	character again, which by default is "p".
+
+	This original program requires a BSD-style interval timer and
+	and new BSD signal interface.  If you are using System V.3
+	or earlier, for example, you will need to make "tromp.s5" 
+	instead of "tromp".  You can change the default make rule 
+	by changing "tromp" to "tromp.s5" in the "WINNERS=..." line
+	of the Makefile.
+
+	The "tromp.s5" version is not as functional as "tromp".  
+	The "drops_per_sec" is ignored and defaults to 1.  The level 
+	is always reported as 0.
+
+	As was stated last year, we are likely to be more strict about
+	portability in the future.  [ We mean it this time :-) ]
+
+Selected notes from the author:
+
+	This program plays the familiar game of `TETRIS' with the
+	following features:
+
+	    * outputs vt100-like escape-sequences for cursor 
+	      positioning and normal/reverse video in curses 
+	      like fashion (minimal output for screen updates)
+
+	    * continuously increasing speed (except in pause)
+
+	    * start speed selectable by giving n as first argument, 
+	      where n is the number of drops per second (default=2).
+
+	    * controls also selectable by giving as the second argument 
+	      a string of 6 characters.  By default they are "jkl pq".
+
+	    * screen is blanked during the pause and the score is shown
+
+	    * maintains a high-score table
+
+	Giving a full path name for the table will result in a
+	system-wide hiscore allowing a competition between users.
+
+The author provided us with the following notes and new version of
+the program:
+
+	Here is a somewhat improved version of my tetris entry.  All the 
+	changes are in the popen() at the end.  Formerly a move was done 
+	to the HI score file which is not permitted for other users. Now 
+	other users can change the HI score file.  The extra option -m is 
+	passed to sort, so that it knows that its input files are already 
+	sorted.  The -o output option of sort is used instead of a 
+	temporary file.
+
+	You may also want to consider giving just the raw option to stty
+	at the start and -raw at the end. This further reduces the size of
+	the program, but has the possible disadvantage that the program
+	can only by stopped by 'q' or by the `kill -9' command.
