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.

+	Pagine Corporation
+	1961-A Concourse Drive
+	San Jose, CA 95131
+	USA
+
+## To build:
+
+        make all
+
+NOTE: this entry requires `X11/Xlib.h` header file and the X11 library to
+compile. The Makefile sets the additional paths to `/opt/X11/include` (`-I`
+flag) and `/opt/X11/lib` (`-L` flag) but you can override it by specifying e.g.:
+
+	make X11_INCDIR=/opt/local/include X11_LIBDIR=/opt/local/lib/ all
+
+which could compile it under macOS with MacPorts if you have the right packages
+installed though it still must be run on an X11 server which means that the
+example is just that: an example which might or might not work when running.
+
+### To run
+
+    DISPLAY="your_X_server_display" 
+    export DISPLAY
+    ./cmills [speed]	# must be run on an X11 server
+
+    where:
+
+	speed	update speed from 1 to 9 (default is 9)

+## Judges' comments
+
+    From the San Jose Mercury News (May 15, 1993 page 20A "West Hackers 
+    trounce East in computer quiz game"): 
+
+	"Since 1984, a contest has been held on Usenet for the most
+	unreadable, creative, bizarre but working C program", Gates
+	said. "What is the name of this contest?"
+
+	"Windows," shot back Gassee, naming Microsoft's premier product
+	- a product over which Apple sued Microsoft five years ago. Not
+	the right answer - it's "The Obfuscated C Contest [sic]" - but
+	it brought down the house of Apple partisans...
+
+    [The expression on Bill Gates' face was a sight to behold, as reported
+    to us by several who were there].
+
+    You must set $DISPLAY in your environment or the program will 
+    dump core.  This is not a bug as the author documented it as
+    a feature.  :-)
+
+    The optional argument is integer which controls the speed of the
+    program.  By default the speed is 9.  You may want to try 1.
+
+    You will have to kill the program (i.e., ^C) to stop it.
+
+    WARNING: Slow servers or servers with long request queues will
+	     continue to 'run' for a while after you have killed
+	     the program.
+
+    This program makes your windows about as useful as their windows. :-)
+
+## Author's comments
+
+    The program uses a single backing pixmap (which is the size of the
+    screen) for all of its subwindows (with a little bit of trickery to
+    move the offset around).  This is much better (and faster) than the
+    obvious implementation which would require a full-screen pixmap and
+    a separate backing pixmap for each subwindow.
+
+    The chance that a window breaks is based on it's kinetic energy,
+    which in turn is based on it's area and speed.  How silly!
