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.

+(it resulted in a bus error otherwise). Thank you Yusuke for your assistance!

+## Author's comments
+
+This is a blackjack program.  It does splits, doubling down,
+insurance, etc.  
+
+As best I can figure, it should be ANSI-compliant, as well as
+portable to BSD & sysV (as well as the irritating compiler I
+was using which assumes `x=*p++` means `x*=p++`!).  It is
+reasonably robust in its error handling---it won't let you
+split, double, etc. unless you actually have the cash, etc.  To
+terminate the program, hit EOF or type 0 or a negative number
+for you wager.
+
+The way it deals with splits is particularly cool (IMHO).  You
+can split many times, and it will show all hands as they are
+played.
