I agree that warnings are not for such things.  Emacs too
often uses "warnings" for things that are not warnings.

On the other hand, I do appreciate this highlighting, though
at first I didn't think I would.  I think a different face
should be used for this - this is *warning* about anything.
That would let users control whether it is actually highlighted
(e.g., by resetting the face attributes to nil).

This is a duplicate of bug #18163, BTW.  And the thread
repeats that one...
