Right.  It was very difficult to find where that warning was coming from.
It turns out that searching for a comma finds lots of matches that
do not represent anything wrong.

The mew warning (shown first above) is better), so I'd suggest disabling
the old (second) warning for this function.

It would be useful to improve the "function XYZ is not known to be defined"
warning in that way -- but, in the special case of comma, the newer
more specific warning is better.
