The actual text is fine — I'm just inclined to read the topmost line first:
...to return `FnMut` instead of `Fn`
you might have to change this...

I kept the span for the method ident with no label and shortened the wording to change this to return FnMut instead of Fn, as it seems more consistent with the terseness of the other suggestions we give.
