Format/typo check 1990/cmills

I included a link in the judges' remarks written by Dennis Ritchie about
C history in order to explain something the author noted, that I felt
some might find interesting. It was stated:

    ... as well as the irritating compiler I was using which assumes
    x=*p++ means x*=p++ !

but the explanation is quite simple. In early C and also B the compound
assignments had the = first so that:

    x += 5

used to be written as:

    x =+ 5

This is also shown in Lions' Commentary on the Sixth Edition UNIX
Operating System but not linked, only referenced. Both the document and
the book are quite fascinating.

 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.
