Not my preference, but that is my proposal, in the interest

Not unsilenceable - but on-by-default.  It could be silenced with
an explicit -Wno-comment.  (Or whatever mechanism we use to
control warnings.)

The point is that since it's silly and dangerous to depend on
trailing whitespace, and it's normally a mistake, we should
warn about it even without -Wall, but if people really want to
live dangerously they can turn it off.

They can use -Wno-comment.
