Hello

I noticed that for the function below the docstring doesn't match the
arg names.  I've chosen to keep the docstring on the basis that it may
be what has been the most visible for a time, and update the names in
the code.

In general, is it TRT?  Do we have a convention to keep names or the
docstring.  Please let me know if this patch is useful in its current
form or a change is needed.

thanks
Jeremy
