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.

+    Nearly every year, one or more people would submit what they claimed 
+    was the world's smallest self reproducing program.  While the sizes
+    of these submissions varied, a quick glance would reveal that they
+    were too big, until this entry came along.
+
+    While strictly speaking, smr.c is not a valid C program, it is
+    not an invalid C program either!  Some C compilers will compile
+    an empty file into a program that does nothing.  But even if your
+    compiler can't, the build instructions supplied with this entry
+    will produce an executable file.  On most systems, the stdout
+    from the executable will exactly match original source.
+
+    In the future, the contest rules will specify a minimum size
+    that is one character larger than this entry, forever eliminating
+    this sort of program from contest.  After all, how many variations
+    can one make on this entry?  :-)

+Selected notes from the author:
+
+    The world's smallest self-replicating program. Guaranteed.
+    Produces a listing of itself on stdout.
