I agree with Henry.  There are few "proper" uses of a comma operator.
The comma operator, since it is vastly underused tends to confuse most
programmer, even competent ones.  Besides, there are more intuitive ways to
write most code which would require a comma.

The code above could be written as 

	while (c = getchar && c  != EOF) { 
	    ... 
	}

Which most programmers would find "more intuitive" than the comma seperated
one.
