Sure. Since the patch simply using warning_at is trivial and anyway
warn_about_parentheses is currently shared with the C front end, I propose to
just do that for 4.8.0. I'm attaching what I have regtested. I think it would
be a definite improvement. Tell me what you think. If you disagree, no problem,
I can move to something else and completely delay this issue to a later time.
