Roll back ad04d21fda

As was discussed with Landon this was a mistake even if it helped with
consistency. There was even a brilliant pun that was destroyed with that
commit which I think is worth pointing out:

    cp README.md hill
    ./ant hill

in 1991/ant ... even if it's technically 'anthill'.

I hope that I got all links fixed in years.html and winners.html. As
well I tried to make sure I got all handles fixed in all/summary.txt.
Nevertheless these should be checked. For some handles they were never
updated (at least in the html files - though maybe summary.txt too, not
sure) in the first place so there was nothing to do.

Typo fixes like references to *.hint when it should be README.md. There
probably are others that need to be fixed but haven't been located yet.

+## Author's comments
+
+    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.
