           Summary: Clarify note on division by negative zero (editorial)

In Section 6.2.4, op:numeric-divide, we read "Division by negative zero 
returns -INF ..." and we also read "Zero divided by zero ... returns NaN." 
There is a potential for confusion about which rule applies in certain cases. 
Proposal: replace the last sentence in the Note in this section as 
follows: "Positive or negative zero divided by positive or negative zero 
returns NaN. Also, INF or -INF divided by INF or -INF returns NaN."

(This clarification is consistent with IEEE 754, which is normative. The Note 
at the end of Section 6.2.4 is simply provided for the convenience of the 
reader.)
