--- Comment #3 from David Malcolm <dmalcolm at gcc dot gnu.org> ---
As Jakub notes, it's a deletion fix-it hint.

It's suggesting the deletion of the same range as that of the primary location
of the diagnostic, so arguably there's some redundancy there.

I wonder if there's a better way to present this information, but I don't have
any ideas at the moment.
