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.

+Judges' comments:
+
+    To use:
+	make ant
+	./ant 'ERE' [file ...]
+
+    where:
+	ERE 	is an extended regular expression
+	file	a file to process (default is stdin)
+    
+    You may also want to try the author's test suite:
+	make -f ant.test.mk
+    
+    See the author's Posix P1003.2-like documentation file ant.txt
+    for more information.
+
+    This program demonstrates that Posix doesn't guarantee readability.  :-)

+
+Selected notes from the author:
+
+    Some of the features of my entry are:
+
+       o  "Lengthy" POSIX.2 style specification and manual :) :) 
+       o  Useful subset of POSIX.2 Extended Regular Expressions.
+       o  Recursive ERE parser/compiler that generates an NFA railroad. 
+       o  Lazy NFA to DFA evaluation to improve performance speed.
+       o  Code tested on a variety of platforms.
+       o  Make driven test script.
+       o  Can be compiled with ANSI or K&R C.
+       o  Not a toy, but actually useful and usable on systems that use DOS.
